Question 2: What is the role of gold? Gold, this precious metal has the magic of magic, it is rare, precious, value stability, is a symbol of wealth and identity, has always been the goal of people and the status of the pursuit of the everlasting. Everyone knows that owning gold is the same as owning wealth, which is determined by the unique characteristics of gold, so it has been mainly used as financial reserves, currency, jewelry. Of course, the use of gold is not limited to these areas. Gold's luxury makes since ancient times, everyone will be used as jewelry decoration. And the monetary commodity property of gold determines that gold is widely used for financial reserves. Because of its excellent characteristics, gold has historically served as a monetary function, such as a measure of value, a means of circulation, a means of storage, a means of payment and a world currency. In addition, gold is also used in industry and science and technology. As gold has a unique perfect nature, it has a very high corrosion stability; good electrical and thermal conductivity; gold nuclei have a large capture neutron effective cross-section; on the infrared reflectivity close to 100%; in the gold alloys with a variety of catalyst properties; gold also has a good process, very easy to process into ultra-thin gold foil, micron gold wire and gold dust; gold is easy to be plated on other metals Gold is easy to plating to other metals and pottery and glass on the surface, in a certain pressure gold is easy to be fusion welding and forging welding; gold can be made into superconductors and organic gold and so on. Just because there are so many beneficial properties, so that it has reason to be widely used in the most needed modern high-tech industry, such as electronic technology, communication technology, space technology, chemical technology, medical technology and so on. And with the socio-economic development, the economic status and application of gold is constantly changing. Since the 1970s gold and the dollar decoupled, the monetary function of gold in the weakening, in addition to financial reserves and other functions, gold investment function gradually revealed, gold investment began to rise, gold as a kind of investment goods are used by investors in the field of investment. Choosing to invest in spot gold is a good choice sense of interest +110 2314 786
Question 3: Why does gold have a health effect on the body? Wearing a gold necklace can inhibit heart disease, a congenital heart disease told me That friend with congenital heart disease said that after she brought a gold necklace, heart disease never committed. I then have more serious chest tightness, and then like silver, hate the 24K gold cheesy yellow, but in order to cure the disease, take it, I only have a very thin 14 enamel gold necklace, wear a month or so, years of chest tightness and sighing really good. This was all in the late eighties. A few years later, there is a World Wide Web, in the Internet to find the English language of various minerals, gemstones (folklore) medical effects, but also really see the gold on the heart has a healing effect. Those with poor heart function could try it, and it didn't cost much anyway. If it really works, spread the word widely to benefit the public. After I tried astermatch's suggestion, I found it really good. I used to have heart palpitations, but I really haven't had them since I got the gold necklace. Of course, you can't go to bed late and drink coffee every day. I checked in the book, found that gold on the human circulatory system, especially the heart has a very good regulatory role, the book also wrote that gold can strengthen the vitality and energy, strengthen the confidence and power of action. Gold can also strengthen the health effects of other gemstones, no wonder the Chinese and Western traditions have gemstones set in gold to wear, the original is a very deep reason. In addition, gold also has a good preventive effect on arthritis, many patients with arthritis, wear gold wedding ring that finger but only without arthritis.
Question 4: What is the role of gold? To start from the nature of gold
Gold
Gold is a precious metal, is one of the earliest human discovery and development and utilization of metal. It is an important raw material for making jewelry and coins, but also an important national reserve material, known as the king of metal. It is not only regarded as a symbol of beauty and wealth, but also with its unique value, to benefit human life. With the development of science and technology and modern industry, gold in cosmic navigation, medicine, electronics and other industrial sectors, increasingly playing an important role. The use of gold is more and more extensive, the consumption is also more and more large, thus causing the world's countries on the gold of extra concern and strong interest.
Gold in the periodic table of chemical elements in the atomic number 79, atomic weight of 197. gold is very heavy, but lighter than platinum. The density of gold is 19.32 g / cm ′, that is, the diameter of only 46 millimeters of gold balls, the weight of 1 kilogram. Pure gold is golden yellow, but in nature, pure gold is very rare. The color of gold changes with the content of impurities: silver and platinum can make the color of gold pale; copper can make the color of gold darker. Colloidal gold according to its degree of dispersion and microviscous structure of different and show different colors.
The ductility of gold is good, one or two pure gold can be hammered into ten thousandths of a millimeter thick gold leaf, which can be plastered over an area of nine square meters. Gold leaves show transparent, sunlight through, can show green light. 50 grams of pure gold can be drawn eight kilometers, finer than a hair (# 1.6 road, human hair 7 road). Gold volatility is small, generally melting volatility is negligible, in the gas evaporation of gold loss for six times in the air, in carbon monoxide loss of gold in the air twice, the volatility of gold and its impurity content has a great deal to do with the rate of volatilization.
Gold has good electrical and thermal conductivity. Gold's electrical conductivity is second only to silver and copper Bean in the third place in the metal, thermal conductivity of silver 74%. Gold's chemical properties are very stable. Gold at low or high temperatures are not directly oxidized by oxygen. At room temperature, gold and separate inorganic acids (such as hydrochloric acid, nitric acid, sulfuric acid) are not effective, but mixed acids, such as aqua regia (three hydrochloric acid and a nitric acid) and cyanide solution can well dissolve gold. The melting point of gold is 1063°C. If the gold is heated to near the melting point, gold can be fused like iron, fine gold particles can be fused into a block, and gold powder at lower temperatures, must be pressurized before they can be fused together. Gold can be formed with other metals alloy, such as gold-silver alloy, gold-copper alloy, gold-silver-copper alloy. In addition, there is the so-called gold-mercury alloy.
Gold often exists in the state of natural gold. Containing silver and copper impurities in the natural gold and these metal alloys are fundamentally different, the alloy is the product of metal melting and solidification, so it has a homogeneous structure, the natural gold is precipitated from the aqueous solution. Natural gold is sometimes covered with a film of iron oxide. In this case, the color of gold may be brown, dark brown, or even yellow. This kind of gold generally have a parcel layer, this parcel layer is not only iron oxide, sometimes may be some attached to the surface of the gold grains of fine-grained chalcopyrite. This kind of inclusions not only affect the identification of gold, but also make it more difficult in the beneficiation (amalgamation or cyanidation) treatment.
Gold as the king of hardware, gold is one of the few chemical, physical and electronic properties of the metal, the application of a very wide range of electronic, communications, aerospace, chemical, medical and other sectors and people's daily life related to all kinds of daily necessities have a wide range of applications.
The rapid development of the modern electronics industry, the reliability of the requirements of more and more high, and gold has other metals can not be replaced by high stability. At the same time, the increasing miniaturization of electronic products, the unit amount of gold will be very small, the cost of the product is not a threat. Therefore, more and more electronic components can use gold as raw materials.
Gold due to high temperature, corrosion resistance and other characteristics, in the aerospace field is also a large number of applications, with a large number of aerospace technology applied to the people, gold in these aspects of the market outlook is very optimistic. For example, a gold-plated glass, used in aerospace for UV protection, can now be applied to the building, can play a very good role in preventing solar radiation and heat insulation.
Gold can also be used for daily necessities, such as gold-plated clocks, belt buckles, lighters, pens and so on. Watch Kingdom of Switzerland is not a large country, but its jewelry industry each year with about 40 tons of gold, 95% of which are used in the watchmaking industry. Japan only a watch factory a year consumption of gold salt up to 1 ton, equivalent to the consumption of gold 680 kilograms. With the improvement of our people's living standards, electroplating with gold prospects will be very broad.
Gold has a very high corrosion resistance stability, good electrical conductivity and thermal conductivity. The nucleus of gold ...... >>
Question 5: What are the main uses and characteristics of gold? Uses:
1). Used as an international reserve. This is determined by the monetary commodity properties of gold. Due to the excellent characteristics of gold, historically gold acts as a monetary function, such as the scale of value, circulation means, means of storage, means of payment and world currency. Since the twentieth century 70s gold and the dollar after decoupling, gold's monetary function has also weakened, but still maintain a certain monetary function. At present, many countries, including the major Western countries in the international reserves, gold still occupies an important position.
2). Used as jewelry decoration. Gorgeous gold jewelry has been a symbol of one's social status and wealth.
Application in industry and science and technology

3, gold in the application of electrical contact materials
In modern communication systems, control systems and electronic computer systems, although its structure is compact, device miniaturization, but should also ensure that the possibility of the necessary checks.
4, gold in the application of conductive materials
Jinshi, gold foil, gold powder pressed into parts, gold alloy, gold alloy materials (such as gold-covered glass, gold-covered ceramics, gold-covered quartz), etc. are widely used as conductor materials for electronic equipment, semiconductor devices and microcircuits to do conductor materials.
5. Gold in the application of gold-based solder
Gold-based solder has many valuable properties, just because the price of gold is expensive and limit its industrial applications in large quantities. With the electronics industry, vacuum technology, atomic energy devices, aircraft and rockets with jet engines, aerospace devices and other new structural materials development work, the application of gold-based solder has become more broad.
6, gold in the application of electronic paste
1960 the rise of integrated circuits developed very quickly, in 1967 and 1977 there have been large-scale integrated circuits and ultra-large-scale integrated circuits came out. Integrated circuits have not only become the basis for a variety of advanced technologies.
Features:
The color of gold is golden yellow, metallic luster, no resolution. Hardness 2-3, pure gold 19.3, melting point 1070 ℃; with good ductility, can be pressed into a thin foil, with very high heat transfer and electrical conductivity, pure gold is the best electronic conductor material.
Gold as a precious metal, has good physical properties, "real gold is not afraid of fire" means that the general flame gold is not easy to melt. Density, feel heavy. Good toughness and ductility, good conductivity. Pure gold has a brilliant yellow, but mixed with other metals, the color changes, such as gold-copper alloy is dark red, silver alloy is light yellow or off-white. Gold is easy to be ground into powder, which is the reason why gold is dispersed in nature, pure gold jewelry is also easy to be worn and reduce the portion.
Question 6: What are the benefits of wearing a gold necklace? Wear gold necklace storage what special benefits, the so-called health care effect is only minimal, that is, a kind of show off the rich mentality. However, the chemical elements of gold is very stable this is not false, the value of the ability to see ****.
And wearing a gold necklace will be noticed by many people, such as thieves, robbers.
As the saying goes, not afraid of thieves stealing, afraid of thieves thinking.
If you want to health care, such as long hours sitting in the office, playing mahjong, etc., then wear a magnetic therapy collar can be, this collar domestic all fake, no effect, only the original Japanese imports of the Magneloop brand to be effective, really is to promote the neck near the accelerated blood circulation, it is very good to use.
Question 7: What are the benefits of men with gold Gold and silver are rare alloy metals, with a more stable chemical properties, not easy to deteriorate, can maintain its external shape for a long time, is not easy to deform, has a very good ornamental value, while wearing on the human body is not easy to friction caused by skin infections and lesions, so for a long time, people began to use them to make jewelry, worn directly on the body. On the body. There are also social legends about the wearing of gold and silver jewelry can avoid evil spirits, sedative effect.
What are the benefits of wearing a gold ring? Wearing a gold ring is just for decoration? Wearing a gold ring is not like wearing jade, tourmaline, as these, the body has certain benefits? Most people buy gold is to figure his decorative role and investment value, in fact, wear gold jewelry, on people's health, enhance the human temperament and so on, also has a lot of benefits.
Gold metal is suitable for making rings. Gold, its chemical composition is stable, made out of the ring can be long to maintain the appearance of the same, and not easy to deteriorate. Wearing a gold ring can enhance the richness of people, because the original gold is rich people can wear jewelry, with the improvement of living standards, more and more people to buy gold, which is also a status symbol, but also shows the progress of people's material standard of living.
From the health point of view of analysis, wearing a gold ring is also beneficial. Because the ring and the skin is always in a state of friction, thus promoting blood circulation in the hand, so the benefits of wearing a gold ring is also manifested in the reduction of skin infections. The human ring finger has a meridian called Sanjiao meridian, the human body produces hormones mainly by this meridian transportation. When the ring finger wearing a gold ring, this meridian can produce *** the role of *** the Sanjiao meridian, so that it is always active and smooth state.
In addition to the physical benefits, the benefits of wearing a gold ring are also manifested in the exorcism, calming. In fact, wearing gold can also be reflected from the reverse side of personal health, if the body does not have disease, healthier people wear gold jewelry, gold will be more shiny, but if the physical quality is not good people, wear gold can not guarantee that the color of gold so good, but this is what people think, and there is no scientific basis. The human body has no disease, or should use scientific means, the hospital to do a detailed examination only.
Question 8: What is the effect of golden oil? Hardness is not enough, not easy to get an erection, not enough lasting nemesis
Question 9: What is the role of gold in finance? Gold has played a very big role in the history of finance, and there is a lot that can be said about it.
When we talk about gold, we have to talk about the gold standard. The time is 1880 to 1914 or so
Gold as a hard currency has been unchanging for a long time. When countries issued paper money, what made people think your paper money was worth so much money? Will my paper money become waste paper because you are cheating?
The so-called state of the day dictated by law how much gold was in my currency.
The country then had a law that stated how much gold was in its currency, and how much gold I had, and how much my currency was worth.
In other words, paper money was not only backed by the state's credit, but also backed by enough gold. The currency of a country with a lot of gold was worth more, and the currency of a country with less gold was worth less.
But when the financial crisis hit, everything changed.
Why? Because paper money can become real paper, not because of the reduction of gold. It's the impact of the financial crisis.
We know that money in the bank has a magnifying effect. When your money in the bank, the bank will not really give you the money to hide well to, but will be your money out of credit, so the money will continue to be magnified. As long as the bank makes sure that there is enough money available to you when you come to withdraw your money, it will be fine.
But when people want to get their money out of the bank, no amount of money will satisfy them, because the bank has already lent their money to someone else. When the bank couldn't get the depositors to withdraw their money, the bank failed. All the deposits of the bank are lost because of the failure. And it affects other banks.
When the crisis comes, even the whole world is affected. What is the most useful thing to preserve the value? That's right, gold.
That's why many countries started to buy gold, because it was free to move on the gold standard.
So a lot of big gold holders couldn't take it. Britain was the first country to go off the gold standard. This was followed by a number of other countries.
The gold standard came to an end.
Then came the role of gold after World War II.
We know that the United States was the biggest beneficiary of World War II, and it was a powerful country.
We know that the United States was the biggest beneficiary of World War II, and it was very powerful. In the Bretton Woods system, the dollar was pegged to gold
which means that one ounce of gold was equal to 35 dollars.
But this system failed again in the unstable economic turmoil of the 1960s in the United States.
Now. Gold is used as a means of preserving the value of the natural man in society. People who are under pressure from inflation and want to make sure that their money doesn't go down in value buy gold.
Because gold is valuable at all times. Just because you devalue your paper money, it doesn't mean that my gold will be devalued as well.
On the other hand, we see the role of gold in the futures market. Gold is also sold as a product in the futures market, and because of its rarity, it is favored by many people,
Now the price of gold is also subject to fluctuations in these markets.
Gold generally plays such a role in society. I hope this helps...!
