What is Cobalt?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Cobalt which has developed particularly rapidly in recent years. Do you know about Cobalt?
The official answer: Cobalt (Cobalt) [1] [13], element symbol Co, silvery-white ferromagnetic metal, silvery white with a slight pink color on the surface, located in the periodic table in the periodic cycle, group VIII., atomic number 27, atomic weight 58.9332, arranged hexagonal crystals, common compound valence of +2, +3. Cobalt is a shiny steel-gray metal, hard and brittle, ferromagnetic, and the magnetism disappears when heated to 1150 ° C. It does not work with water at room temperature and is also stable in humid air. It is oxidized to form CoO when heated to above 300 °C in air and burned into Co3O4 when it is white-hot. The fine metal cobalt powder made by the hydrogen reduction method can combust in the air to generate cobalt oxide. Cobalt is an important raw material for the production of heat-resistant alloys, cemented carbide, anti-corrosion alloys, magnetic alloys and various cobalt salts.
What’s the application of Cobalt?
The physical and chemical properties of cobalt determine that it is an important raw material for the production of heat-resistant alloys, cemented carbide, anti-corrosion alloys, magnetic alloys and various cobalt salts. Cobalt metal is used to prepare alloys.Cobalt is not only an important metal for the manufacture of alloy steel, but also an important raw material for various high-grade pigments.Cobalt is a component of vitamin B12, and ruminants can synthesize the ingested cobalt into vitamin B12 in the intestine, while humans and monogastric animals cannot synthesize cobalt in the body to synthesize B12.
