Product: Cobalt Tetroxide
Chemical formula: Co3O4CAS number: 1308-06-1
Cobalt tetroxide, black or gray-black powder. Loose density 0.5-1.5g/cm3, vibration density 2.0-3.0g/cm3. It is a product of cobalt monoxide and cobalt trioxide. When exposed to air, it is easy to absorb water but does not form hydrates. It is readily soluble in nitric acid. When heated above 1200 ° C, it will decompress into cobalt oxide. Upon intense heat to 900 ° C in a hydrogen flame, it is reduced to metallic cobalt.
1. It is mainly used in the battery industry, but also as an oxidant and to make enamel.
2. Used for catalyst and oxidant.
3. Used in the manufacture of cobalt salt and enamel pigments.
