Chemical Properties:
Exposure to air, easy to absorb moisture, but does not generate water compounds. It is soluble in nitric acid. When heated to above 1200 oC, nano-cobalt oxide will be broken down into sub-cobalt oxide. In the hydrogen flame, nano-cobalt oxide is heated to 900 oC, it will be transformed into metal cobalt. Cobalt(II,III) oxide is chemical compound with the formula Co3O4. It is a black solid, and a mixed valence compound, containing both Co(II) and Co(III) oxidation states. It can be formulated as CoIICoIII2O4 or CoO.Co2O3. Cobalt(II) oxide, CoO, converts to Co3O4 if heated to around 600-700 °C in air. Above 900 °C, CoO is stable.
Applications:
Catalysis, superconductors, ceramics, etc.
