Tricobalt tetroxide

Cobalt(ll) oxide is prepared by heating cobalt(lI) carbonate, C0CO3, cobalt(lll) oxide, C02O3 or tricobalt tetroxide, C03O4, at high temperatures in a neutral or slightly reducing atmosphere ... [Pg.248]

Strong heating in air converts cobalt(III) oxide to tricobalt tetroxide. Reactions with mineral acids produce their Co3+ salts ... [Pg.249]

Tricobalt tetroxide is a minor component of commercial cobalt oxides. It is used in ceramics, pigments, and enamels. Other applications are in grinding wheels, in semiconductors, and for preparing cobalt metal. [Pg.252]

Tricobalt tetroxide is obtained when cobalt(ll) carbonate, cobalt(ll) or cobalt(III) oxide, or cobalt hydroxide oxide, CoO(OH) is heated in air at temperatures above 265°C. The temperature must not exceed 800°C (see decomposition temperature above). [Pg.252]

Tricobalt tetroxide absorbs oxygen at lower temperatures, but there is no change in the crystal structure.)... [Pg.252]

The compound is readily oxidized in air to form tricobalt tetroxide, C03O4, and is readily reduced by hydrogen to the metal. [Pg.173]
