Izakhiwo:
Ukuchayeka emoyeni, kulula ukumunca umswakama, kodwa akukhiqizi izinhlanganisela zamanzi.Iyancibilika ku-nitric acid.Uma ishiswa ngaphezu kuka-1200 oC, i-nano-cobalt oxide izohlukaniswa ibe i-sub-cobalt oxide.Elangabi le-hydrogen, i-nano-cobalt oxide ishisa ku-900 oC, izoguqulwa ibe yi-cobalt yensimbi.I-Cobalt(II,III) oxide iyinhlanganisela yamakhemikhali enefomula ethi Co3O4.Iqinile emnyama, kanye nenhlanganisela ye-valence exubile, equkethe kokubili izifunda ze-Co(II) kanye ne-Co(III).Ingenziwa njenge-CoIICoIII2O4 noma i-CoO.Co2O3.I-Cobalt(II) oxide, i-CoO, iguqulela ku-Co3O4 uma ishiselwa cishe ku-600-700 °C emoyeni.Ngaphezu kuka-900 °C, i-CoO izinzile.
