Kayayyaki:
Fuskantar iska, mai sauƙin ɗaukar danshi, amma baya haifar da mahaɗan ruwa. Yana narkewa a cikin nitric acid. Lokacin da zafi sama da 1200 oC, nano-cobalt oxide za a rushe zuwa sub-cobalt oxide. A cikin harshen wuta na hydrogen, nano-cobalt oxide yana mai zafi zuwa 900 oC, za a canza shi zuwa karfe cobalt. Cobalt(II,III) oxide wani abu ne na sinadarai tare da dabarar Co3O4. Baƙar fata ce mai ƙarfi, kuma gauraye valence fili, wanda ya ƙunshi jihohin Co(II) da Co(III) oxidation. Ana iya tsara shi azaman CoIICoIII2O4 ko CoO.Co2O3. Cobalt(II) oxide, CoO, yana jujjuyawa zuwa Co3O4 idan mai zafi ya kai 600-700 °C a cikin iska. Sama da 900 °C, CoO yana da ƙarfi.
