Awọn ohun-ini:
Ifihan si afẹfẹ, rọrun lati fa ọrinrin, ṣugbọn ko ṣe ina awọn agbo ogun omi. O jẹ tiotuka ninu acid nitric. Nigbati o ba gbona si oke 1200 oC, nano-cobalt oxide yoo fọ lulẹ si oxide sub-cobalt. Ninu ina hydrogen, nano-cobalt oxide ti gbona si 900 oC, yoo yipada si koluboti irin. Cobalt(II,III) oxide jẹ idapọpọ kemikali pẹlu agbekalẹ Co3O4. O jẹ ri to dudu, ati agbo valence adalu, ti o ni awọn mejeeji Co (II) ati Co (III) awọn ipinlẹ ifoyina. O le ṣe agbekalẹ bi CoIICoIII2O4 tabi CoO.Co2O3. Cobalt(II) oxide, CoO, yipada si Co3O4 ti o ba gbona si ayika 600-700 °C ni afẹfẹ. Ju 900 °C, CoO jẹ iduroṣinṣin.
