Cobalt Oxide

Cobalt oxide is Black or gray crystal. It can absorb water and form hydrate, but has no fixed composition. It is easily reduced to cobalt by carbon, carbon monoxide or hydrogen. When the oxygen is lost above 900℃, it becomes cobalt monoxide, which can absorb oxygen at lower temperatures, and the crystal structure is unchanged. Soluble in acids and bases, almost insoluble in water. Density: 6.11 Melting point :895 °C.

Cobaltous Carbonate Application:

Mainly used for battery materials, magnetic materials, thermistors, catalyst mechanism for enamel.

It is used for the preparation of high purity analytical reagent, cobalt oxide and cobalt salt.

Used for lithium electron cathode material, cobalt oxide and cobalt salt preparation.
