Chrome oxide is a green crystal powder, metal luster, magnetic, good covering strength, high-temperature-resisting and sunlight fastness. Not soluble in water, barely soluble in acids, comparatively stable in air, unaffected by acids and alkalis of common density, sulfur dioxide, sulfur hydrogen etc. Chrome oxide green enjoys excellent quality and firmness of coloring.

Insoluble in water, acid and organic solvents, slightly soluble in concentrated sodium hydroxide solution, sodium bromide dissolved in hot, hot or boiling concentrated perchloric acid solution of parathion mixed acid.

With careful and highly advanced process, we manufacture high purity Chromium Oxide which is widely used in Schools, Universities, Colleges and R & D firms for testing. They are used as a catalyst in the preparation of methanol, butadiene and high density polyethylene. Chromium also has some use in the manufacture of certain chemicals. For example, chromium-bearing chemicals are used in the process of tanning leather.
