Industrial Uses Of Cobalt

wallpapers News 2020-12-25
Cobalt, element symbol Co, silver-white ferromagnetic metal, the surface is silver-white and slightly pink, located in the 4th period, group VIII in the periodic table, atomic number 27, atomic weight 58.9332, close-packed hexagonal crystal, common valence is +2 , +3. Cobalt is a lustrous steel gray metal, relatively hard and brittle, ferromagnetic, and its magnetism disappears when heated to 1150°C. The valence of cobalt is +2 and +3.
 
Industrial applications
 
The physical and chemical properties of cobalt determine that it is an important raw material for the production of heat-resistant alloys, hard alloys, anti-corrosion alloys, magnetic alloys and various cobalt salts. Cobalt-based alloys or cobalt-containing alloy steels are used as blades, impellers, ducts, jet engines, rocket engines, missile components and various high-load heat-resistant components in chemical equipment and important metal materials in the atomic energy industry. As a binder in powder metallurgy, cobalt can ensure the toughness of cemented carbide.

 
Magnetic alloy is an indispensable material in modern electronics and electromechanical industries, used to make various components of sound, light, electricity and magnetism. Cobalt is also an important component of permanent magnetic alloys. In the chemical industry, in addition to high-temperature alloys and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, and desiccants. According to the British "Metal Leader" report, the demand for cobalt from the hard metal sector and super alloys is relatively strong.
 
In addition, cobalt has the highest consumption growth rate in the battery sector. According to relevant domestic reports, the application of cobalt in the storage battery industry, diamond tool industry and catalyst industry will also be further expanded, resulting in an upward trend in the demand for metallic cobalt. Individual cobalt deposits are generally divided into three types: cobalt arsenide deposits, cobalt sulfide deposits and cobalt earth deposits.
