Cobalt Oxide

Cobalt Oxide:

1. Product introduction: Cobalt Oxide (Co2O3) is a high-valence oxide of cobalt, with a theoretical cobalt content of 71.06% and an oxygen content of 28.94%. It has a density of 6.079 g/cm³. It is a black amorphous powder that transforms into Cobalt(III) Oxide (Co3O4) upon heating. Cobalt Oxide is an unstable compound and cannot exist in a free state. Typically, the term "Cobalt Oxide" still refers to a compound that contains a certain amount of Cobalt(III) Oxide. Cobalt Oxide is stable only in its hydrated state, and this hydrate will dehydrate and transform into intermediate Cobalt(III) Oxide (Co3O4) at 265°C. Cobalt Oxide can be reduced to Cobalt(III) Oxide (Co3O4) by H2 at 125°C, reduced to CoO at 200°C, and further reduced to metallic cobalt at 250°C. Cobalt Oxide is insoluble in water but soluble in acids, forming corresponding cobalt salts.
