Meatotino:
Fa'aalia i le ea, faigofie ona mitiia le susu, ae le fa'atupuina fa'atasi vai.E solu i le nitric acid.Pe a faʻavevela i luga atu o le 1200 oC, o le nano-cobalt oxide o le a talepe i lalo i lalo-cobalt oxide.I le afi o le hydrogen, o le nano-cobalt oxide e faʻamafanafanaina i le 900 oC, o le a liua i le cobalt uʻamea.Cobalt(II,III) oxide o se vaila'au vaila'au ma le fua fa'atatau Co3O4.O se mea lanu uliuli, ma se faʻafefiloi valence fefiloi, o loʻo i ai uma Co(II) ma Co(III) oxidation setete.E mafai ona faʻatulagaina o CoIICoIII2O4 poʻo CoO.Co2O3.Cobalt(II) oxide, CoO, liua i le Co3O4 pe a vevela ile 600-700 °C ile ea.I luga aʻe o le 900 °C, CoO e mautu.
