Cov khoom:
Tshaj tawm rau huab cua, yooj yim nqus dej, tab sis tsis tsim cov dej sib txuas. Nws yog soluble hauv nitric acid. Thaum kub siab tshaj 1200 oC, nano-cobalt oxide yuav tawg mus rau hauv sub-cobalt oxide. Hauv cov nplaim hluav taws xob hydrogen, nano-cobalt oxide yog rhuab mus rau 900 oC, nws yuav hloov mus ua hlau cobalt. Cobalt (II, III) oxide yog tshuaj lom neeg nrog cov mis Co3O4. Nws yog cov khoom dub, thiab sib xyaw valence compound, uas muaj cov Co(II) thiab Co(III) oxidation xeev. Nws tuaj yeem tsim tau raws li CoIICoIII2O4 lossis CoO.Co2O3. Cobalt (II) oxide, CoO, hloov mus rau Co3O4 yog rhuab mus txog 600-700 ° C hauv huab cua. Tshaj 900 ° C, CoO yog ruaj khov.
