![]() The color of chromium oxide green is similar to that of plant chlorophyll, which can be used in camouflage paint and can be difficult to distinguish in infrared photography.Īlso a large number of used in metallurgy, production of refractory materials, grinding powder.Ĭhromium oxide green can also be used as a catalyst for organic synthesis and is a high-grade green pigment.Ĭhromium oxide green is used as a spectral analysis reagent, organic synthesis catalyst, ceramic glaze color raw material, and the manufacture of chromium alloy and chromium salt.Ĭhromium oxide green can be obtained by thermal decomposition of ammonium dichromate.Ībove ca. Mainly used in special steel smelting tapping mouth, slide mouth and large incineratorĬan be used for ceramic and enamel coloring, rubber coloring, preparation of high temperature resistant coatings, art pigments, ink for the preparation of printed notes and securities. Other important applications are in metallurgy as a component of refractory bricks, abrasives and ceramics and as a catalyst in hydrogenation, hydrogenolysis and many other organic conversion reactions.Ĭhromium oxide green also is used to prepare other chromium salts. ![]() ![]() In abrasives, refractory materials, electric semiconductors as pigment, particularly in coloring glass in alloys printing fabrics and banknotes as catalyst for organic and inorganic reactions.Ĭhromium oxide green is used as pigment for coloring green on glass and fabrics. They are not classified as hazardous materials and are not subject to international transport regulations.Īs long as they are kept dry their utility as a pigment is practically unlimited.Ĭhromium oxide (Cr2O3) is a dull green synthetic inorganic pigment, which can be used in all types of paint systems where high chemical resistance and outstanding light-fastness are required. Chromium oxide green is one of the few single-component pigments with green coloration.Ĭhrome green is a blend of chrome yellow and iron blue pigments phthalochrome green is a blend of chrome yellow and blue phthalocyanine pigments.Īlkali dichromates are used as starting materials for the production of chromium(III) oxide pigments. Chromium oxide green is one of four oxides of chromium, chemical formula Cr2O3.Ĭhromium oxide green is commonly called "chrome green" when used as a pigment however it was referred to as “viridian” when it was first discovered.Ĭhromium oxide green is a very refractory ceramic colorant (even a 50% mix with a high borax frit will not even begin to melt it in a crucible).Ĭhrome oxide is the only stable oxide of the metal chromium.Ĭhromium oxide green is a bright to dark green crystalline powder insoluble in alkalis and acids.Ĭhromium oxide green is manufactured from the mineral Chromite mined in southern Africa, Asia, Turkey and Cuba.Īs with other powerful coloring agents, chrome must be milled fine enough to eliminate specking in glass or glaze.Ĭhromium is a "fast" colorant, meaning can produce strong green colors under all furnace conditions, slow or fast, reducing or oxidizing.Ĭhromium oxide green is also a flat colorant (due to its refractory nature), it usually produces an army helmet opaque green.Ĭhromium oxide green is powerful, typically only 2% will produce a dark color.Ĭhromium oxide green cannot be used to make a metallic glaze.Ĭhrome oxide is usually employed in raw glazes whereas potassium dichromate is used in fritted glazes.Ĭhromium oxide is a bright green, odorless powder.Ĭhromium oxide green pigments are thermally stable and insoluble in water.Ĭhromium oxide pigments, also called chromium oxide green pigments, consist of chromium(III) oxide, Cr2O3,Mr 151.99. Chromium oxide green is among the ten most abundant compounds in the Earth's crust.
