Dichromium trioxide is a chromium oxide.
Chromium(III) oxide is among the ten most abundant compounds in the Earth's crust. It is one of four oxides of chromium, chemical formula Cr2O3. It is commonly called "chrome green" when used as a pigment; however it was referred to as “viridian” when it was first discovered.Chromium(III) oxide 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). Chrome oxide is the only stable oxide of the metal chromium. It is a bright to dark green crystalline powder insoluble in alkalis and acids. It is manufactured from the mineral Chromite mined in southern Africa, Asia, Turkey and Cuba. As with other powerful coloring agents, chrome must be milled fine enough to eliminate specking in glass or glaze.Chromium is a "fast" colorant, meaning can produce strong green colors under all furnace conditions, slow or fast, reducing or oxidizing. It is also a flat colorant (due to its refractory nature), it usually produces an army helmet opaque green. It is powerful, typically only 2% will produce a dark color. It cannot be used to make a metallic glaze.Chrome oxide is usually employed in raw glazes whereas potassium dichromate is used in fritted glazes.
Chromium oxide is a bright green, odorless powder. Chromium(III) oxide pigments are thermally stable and insoluble in water.Chromium oxide pigments, also called chromium oxide green pigments, consist of chromium(III) oxide [1308-38-9], Cr2O3,Mr 151.99. Chromium oxide green is one of the few single-component pigments with green coloration. Chrome green is a blend of chrome yellow and iron blue pigments; phthalochrome green is a blend of chrome yellow and blue phthalocyanine pigments.Alkali dichromates are used as starting materials for the production of chromium(III) oxide pigments. They are not classified as hazardous materials and are not subject to international transport regulations. As long as they are kept dry their utility as a pigment is practically unlimited.CertificatesBasic Info-
