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. Light, air and corrosive gases (H2S, SO2, etc. ) very stable, excellent weatherability.
Properties: 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.
Chromium Oxide Polishing Grade
This is highly suitable for Polishing Precious stones like Emerald, Ruby, Sapphire and many other stones. This material is widely used in polishing various metals and its alloys like stainless steel, copper, brass, zinc and precious metals like Platinum.
Chromium Oxide Laboratory Grade (99.6-99.9% min)
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 Oxide Refractory Grade
Chromic oxide is commonly used in the production of refractory bricks to line metallurgical and glass furnaces and kilns, mortars, ramming mixes, gunning mixes.
Chromium Oxide Ceramic Color Grade
The product is used extensively in the coloration of construction materials. In addition, the pigment can also be used for the coloration of glazes, enamels, glass, or engobes in the ceramic industry.
Chromium Oxide Metallurgical Grade
The principal uses of Chromium are in metallurgical processing of ferrochromium and other metallurgical products to impart corrosion resistance, chiefly stainless steel. This is also used in Chrome Plating and anodizing aluminum.
