Product details

Uses and synthesis of Cobalt Tetroxide powder

Cobalt Tetroxide powder, formula Co3O4. Molecular weight 240.80. Black powder or gray cubic crystal. The relative density of 6.07, heating to 900 ~ 950℃ to lose oxygen to produce cobalt oxide. Exposure to air absorbs water, but does not produce hydration. Cobalt Tetroxide is insoluble in water, slightly soluble in nitric acid to give off oxygen, soluble in hydrochloric acid to give off chlorine, soluble in sulfuric acid. Cobalt Tetroxide is used in the production of cobalt metal, cobalt catalysts, enamels, ceramic pigments, semiconductors, grinding wheels and cobalt salts, as well as as oxidants. Main features: The particle size is uniform, the particle is a complete ball, and the dispersion is good.

Applications/Functions of Cobalt Tetroxide powder

Cobalt Tetroxide powder is mainly used for battery materials, magnetic materials, thermistors, etc. It can also be used as a catalyst mechanism for enamel, etc., and can also be used for the preparation of cobalt oxide and cobalt salt.

Physicochemical Property of Cobalt Tetroxide powder

Cobalt Tetroxide has the formula Co3O4. Molecular weight 240.80. Black powder or gray cubic crystal. The relative density of 6.07, heating to 900 ~ 950℃ to lose oxygen to produce cobalt oxide. Exposure to air absorbs water, but does not produce hydration. Insoluble in water, slightly soluble in nitric acid and release oxygen, soluble in hydrochloric acid and release chlorine, soluble in sulfuric acid.

Production methodprocess of Cobalt Tetroxide powder

Cobalt Tetroxide powder is prepared by heating cobalt carbonate or cobalt nitrate (or cobalt monoxide) at 700 ° C. It can also be decomposed by heating cobaltous salt in the air at 500 ~ 890 ° C, and by decomposing and oxidizing newly formulated cobalt hydroxide in the air at 150 ° C for 24 hours.
