Cobalt oxide Chemical Properties,Uses,Production


Cobalt(II) oxide is used as a pigment for ceramics and paints; for drying paints, varnishes and oils; for coloring glass; as a catalyst; and for preparation of other cobalt salts. The commercial product is a mixture of cobalt oxides.


Cobalt(II) oxide is prepared by heating cobalt(II) carbonate, CoCO3, cobalt(III) oxide, Co2O3 or tricobalt tetroxide, Co3O4, at high temperatures in a neutral or slightly reducing atmosphere: CoCO3 → CoO + CO2


Cobalt(II) oxide is moderately toxic by ingestion and subcutaneous and intratracheal routes.
LD50 oral (rat): 202 mg/kg

Chemical Properties

Black powder


In pigments for ceramics; glass coloring and decolorization; oxidation catalyst for drying oils, fast-drying paints and varnishes; preparation of cobalt-metal catalysts, Co powder for binder in sintered tungsten carbide; in semiconductors.
