Ngosipụta na ikuku, dị mfe ịmịkọrọ mmiri, mana ọ naghị emepụta ogige mmiri. Ọ bụ soluble na nitric acid. Mgbe ikpo ọkụ ruo n'elu 1200 oC, nano-cobalt oxide ga-agbajikwa n'ime sub-cobalt oxide. N'ime ọkụ hydrogen, nano-cobalt oxide na-ekpo ọkụ ruo 900 oC, a ga-agbanwe ya ka ọ bụrụ cobalt metal. Cobalt(II,III) oxide bụ ngwakọta kemịkalụ nwere usoro Co3O4. Ọ bụ ihe siri ike ojii, yana ngwakọta valence agwakọta, nwere ma Co (II) na Co(III) oxidation steeti. Enwere ike ịhazi ya dị ka CoIICoIII2O4 ma ọ bụ CoO.Co2O3. Cobalt (II) oxide, CoO, na-atụgharị gaa na Co3O4 ma ọ bụrụ na ọ dị ọkụ na gburugburu 600-700 Celsius C na ikuku. N'elu 900 Celsius C, CoO kwụsiri ike.
