CAS number: 1308-06-1; RTECS number: GG2500000
Molecular formula: Co2O3.CoO
Molecular Weight: 240.80
Characteristics:
Cobalt oxide is a black and grey powder, odorless, can be solved slowly in hot HCl acid and vitriol. It becomes when exposed in air, but can't hydrate, not solves in water. When heated to 950 centigrade, it turns into CoO2.
