Āhuatanga:
Te mararatanga ki te hau, he ngawari ki te tango i te makuku, engari karekau e whakaputa i nga puhui wai. He wairewa ki te waikawa nitric. Ina whakamahana ki runga ake i te 1200 oC, ka pakaru te waikura nano-cobalt ki te waikura sub-cobalt. I roto i te mura o te hauwai, ka werahia te waikura nano-cobalt ki te 900 oC, ka huri hei konukawata whakarewa. Ko te Cobalt(II,III) te waikura he pūhui matū me te tātai Co3O4. He totoka pango, me te pūhui valence whakauru, kei roto i te Co(II) me te Co(III) te haukura. Ka taea te hanga hei CoIICoIII2O4, CoO.Co2O3 ranei. Ko te konukawata(II) waikura, CoO, ka huri ki te Co3O4 mena ka wera ki te 600-700 °C i te hau. Kei runga ake i te 900 °C, he pūmau a CoO.
