name:Chrome Oxide Green
CAS No: 1308-38-9 EINECS No: 215-160-9
Molecular formula: Cr2O3
Molecular weight: 151.9904
Appearance: Dark green powder with strong coloring power and covering power.
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.
Package and storage:
Chrome Oxide is packed in 25kgs woven bags lined with PE liner or as request.
Stored in an airtight container, in a cool, ventilated place or specified place; Avoid taboo things
Mainly used in green grourd pave paint colorant, smelting metal chromium, chromic carbide and catalyst of organic synthetic chromium. It is used as coloring agent for coloring painting on ceramics and enamelware and imitation leather or building material; It is also used for making sun-proof coating, abrasive, green polishing compound, refractory materials and so onNearly three decades' precipitation and accumulation endows HNGM with incomparable advantages of mechanicals and raw materials. We are always ready to win more affirmation with cost-effective products and services.
