The development of cobalt
In the case of cobalt, the ancient greeks and Romans used its compound to make colored glass to produce a beautiful dark blue.By the 20th century, cobalt and its alloys had been widely used in the electrical, mechanical, chemical, aero***ce and other industrial sectors and had become an important strategic metal.China began to extract cobalt from cobalt ore, nickel ore and cobalt-bearing pyrite in the 1950s.The use of cobalt minerals has a long history. The egyptians used cobalt blue as a coloring agent for ceramic products in the BC period, and cobalt compounds have been widely used in ceramic production since the tang dynasty.Cobalt was first isolated by the Swedish chemist Brandt in 1735 and identified as an element by Bergman in 1780.
The use of the cobalt
At present, the consumption and application of cobalt in the traditional fields are mainly battery Cobalt materials, super heat resistant alloy, tool steel, carbide, magnetic materials;Cobalt, which is consumed as a compound, is mainly used as a catalyst, desiccant, reagent, pigment and dye.Cobalt-60 is a widely used radioactive material widely used in biochemistry for activation analysis.For tracer studies in electroplating, corrosion and catalysis;It is used in medicine for radiological examination and treatment.
Magnetic materials
super heat resistant Cobalt alloy is one of the few metals that can be magnetized once and remain magnetic.Magnetic Cobalt materials is an important functional material, which plays a very important role in the field of electronic industry and high technology.
Carbide and superalloy
Tool steels containing a certain amount of COBALT METAL PIECE can significantly improve the wear resistance and cutting performance of steel. Cobalt combines the carbide grains of other metals in the alloy composition to make the alloy more ductile and less sensitive to i***ct.Especially suitable for high efficiency high temperature engines and steam turbines, cobalt-based alloys are widely used in aero***ce and mode |
