Thepa:
Ho pepesehela moea, ho bonolo ho monya mongobo, empa ha e hlahise metsoako ea metsi. E qhibiliha ka asiti ea nitric. Ha mocheso o ka holimo ho 1200 oC, nano-cobalt oxide e tla robeha ho sub-cobalt oxide. Ka lelakabe la hydrogen, nano-cobalt oxide e futhumala ho 900 oC, e tla fetoloa ho ba tšepe ea cobalt. Cobalt(II,III) oxide ke motsoako oa lik'hemik'hale o nang le foromo ea Co3O4. Ke motsoako o motšo, le motsoako oa valence o tsoakiloeng, o nang le libaka tse peli tsa Co(II) le Co (III) tsa oxidation. E ka etsoa e le CoIICoIII2O4 kapa CoO.Co2O3. Cobalt(II) oxide, CoO, e fetohela ho Co3O4 haeba e futhumatsoa ho isa ho 600-700 °C moeeng. Ka holimo ho 900 °C, CoO e tsitsitse.
