The main roles and uses of argon are as follows:
1, protective gas: the high purity of argon makes it a high-quality protective gas. In metal smelting, welding and other fields, argon can effectively isolate the oxygen and moisture in the air to protect the metal surface from oxidation, thus improving the welding quality and stability of the metal.
2, lighting: high purity argon gas is also widely used in the field of lighting. It can be used as a light source to produce blue-violet fluorescence, which is used to create special lighting effects. At the same time, argon can also be used to fill high-intensity, high-transmittance light bulbs to improve the service life and stability of the bulb.
3, medical: argon in the medical field of the application is gradually being explored. Studies have shown that argon for tumor cells killing effect is stronger than normal cells, so argon is used in the treatment of tumor diseases. In addition, argon gas can also be used to make medical equipment, such as argon ion therapy instrument.
4, science and technology: argon in the field of science and technology applications are also increasingly widespread. Because of its stable chemical properties and good thermal conductivity, argon is used to make electronic components, semiconductor devices and other high-tech products. In addition, argon can also be used to make optical instruments and special glass products and so on.
Characteristics of argon gas:
1, high purity: argon gas is a high-purity gas, its purity is up to 99.99%. This high purity allows argon to provide excellent performance in many applications.
2, colorless and odorless: argon is a colorless and odorless gas that does not have a noticeable effect on human perception. This feature makes argon gas in industrial and scientific and technological applications more hidden, will not interfere with the surrounding environment.
3, chemical stability: the chemical nature of argon gas is extremely inactive, it is difficult to have a chemical reaction with other elements. This stability makes argon gas in many applications can play a protective role in preventing other substances from being oxidized or corroded.
4, good thermal conductivity: argon has good thermal conductivity, can effectively transfer heat. This feature makes argon gas in some areas, such as electronic components manufacturing and semiconductor device manufacturing has a special use.
