Titanium's role:
Because of its stable chemical properties, good resistance to high temperature, low temperature, strong acid, strong alkali, as well as high strength, low density, is known as the "space metal".
Titanium's most common compound, titanium dioxide, is used to make white pigments. titanium dioxide is used to make white pigments. Other compounds include titanium tetrachloride (TCT), which is used to make white pigments. Titanium tetrachloride (TiCl) (used as a catalyst and in the manufacture of? (as a catalyst and in the manufacture of smokescreens or aerial text) and titanium tetrachloride (TiCl). Titanium trichloride (TiCl) (used to catalyze the production of polypropylene). (used to catalyze the production of polypropylene).
Titanium can be combined with? Iron,? aluminum, ? vanadium or? Molybdenum and other elements fused into alloys to create high-strength light alloys, which have a wide range of applications in various areas, including aerospace (jet engines, missiles and? spacecraft), military, industrial processes (chemical and petroleum products,? desalination and paper), automotive, agri-food, medical (prosthetics, orthopedic implants and dental instruments and fillings), sporting goods, jewelry and cell phones, and more.
I, titanium's introduction:
Titanium is a chemical element, chemical symbol Ti, atomic number 22, in the periodic table of chemical elements in the 4th cycle, the IVB group. It is a silvery-white transition metal that is lightweight, strong, has a metallic luster, and is resistant to wet chlorine corrosion. However, titanium can not be used in dry chlorine gas, even if the temperature is 0 ℃ below the dry chlorine gas, will undergo a violent chemical reaction, the formation of titanium tetrachloride, and then decomposed to form titanium dichloride, and even combustion. Only when the water content in the chlorine gas is higher than 0.5% can titanium maintain reliable stability in it.
Two, the physical properties of titanium:
Titanium is an important alloying element in steel and alloys, titanium's density of 4.506-4.516 g/cm3 (20 ℃), higher than aluminum and lower than ? Iron, copper, nickel. But the specific strength is located in the first metal. Melting point 1668 ± 4 ℃, latent heat of fusion 3.7-5.0 kcal / g atoms, boiling point 3260 ± 20 ℃, critical temperature 4350 ℃, ? Critical pressure 1130 atm. Titanium's thermal and electrical conductivity is poor, titanium has superconductivity, at 25 ℃, titanium's heat capacity of 0.126 cal/g atom-degree, enthalpy 1149 cal/g atom, entropy 7.33 cal/g atom-degree, titanium metal is a paramagnetic substance, magnetic conductivity 1.00004.
