.Cobalt symbol Co, silver-white ferromagnetic metal, the surface is silverish white with pale pink, in the periodic table in the 4th cycle, the VIII family, atomic number 27, atomic weight 58.9332, close-packed hexagonal crystal, common valence is +2 +3. Cobalt is a shiny steel gray metal that is relatively hard and brittle, ferromagnetic, and disappears when heated to 1150 °C. The valence of cobalt is +2 and +3. It does not interact with water at normal temperature and is stable in humid air. When heated to 300 ° C or higher in air, it oxidizes to form CoO, and when it is white, it burns to Co3O4. The fine metal cobalt powder produced by the hydrogen reduction method can self-ignite in the air to form cobalt oxide. Cobalt is an important raw material for the production of heat-resistant alloys, hard alloys, anti-corrosion alloys, magnetic alloys and various cobalt salts.
