Request SDS →Chromium(III) oxide (Cr2O3, CAS 1308-38-9) is a stable green inorganic oxide used principally as a colorfast green pigment in paints, inks, glass and ceramics. Its hardness suits it to abrasive and polishing compounds and its thermal stability to refractory materials. It is also used in metallurgy to produce chromium metal and aluminum-chromium master alloys, and as a catalyst.
Frequently Asked Questions
What is chromium(III) oxide used for?
Chromium(III) oxide (Cr2O3, CAS 1308-38-9) is used principally as a colorfast green pigment in paints, inks, glass, and ceramics. Its hardness suits it to abrasive and polishing compounds, its thermal stability to refractories, and it is also used in metallurgy to make chromium metal and aluminum-chromium master alloys, and as a catalyst.
What gives chromium(III) oxide its green color?
Cr2O3 is a stable inorganic oxide whose Cr(III) ions produce a characteristic colorfast green, which is why it is valued as a durable pigment in coatings, ceramics, and glass. The pigment is prized for its lightfastness and chemical stability.
Is chromium(III) oxide water soluble?
Chromium(III) oxide is an inorganic oxide that is essentially insoluble in water, which contributes to its stability and colorfastness as a pigment. Solubility and handling data are in the SDS. Request it for the grade supplied.
What is the HS code for chromium(III) oxide?
Chromium(III) oxide falls under HS 2819.90 (chromium oxides and hydroxides: other). RawSource supplies it as pigment-grade and technical-grade material. Request CoA and SDS for specification and particle-size data.
What is the cost of bulk chromium(III) oxide?
Bulk pricing depends on grade, particle size, packaging, and volume. RawSource quotes industrial quantities directly rather than listing a fixed price. Send your grade and volume requirements for a current quote and lead time.
