Use 1
It is mainly used in special steel smelting outlet, sliding plate outlet and large incinerator
Use 2
Used as catalyst and analytical reagent
Use 3
Used as smelting metal chromium, chromium carbide, polishing paste and paint pigment, also used as enamel, glass, ceramic coloring agent and organic synthesis catalyst
Use 4
Lead chromium green is the main coloring pigment in the paint industry, and most green paints are prepared with this pigment. In addition, it is also used in paints and plastics. Its application range is very similar to that of lead chrome yellow. Because the composition contains chromium yellow, the toxicity of lead should be noted when applied. Lead chromium green contains iron blue, and contains the oxidizing agent lead chromate, so when the dust meets Mars there is the possibility of spontaneous combustion, in the drying, crushing can not be accidentally. After combustion, the lead chromium green completely loses the characteristics of green pigment and transforms into a deep brownish yellow substance. In addition, in the production of nitrocellulose paint, the rolling process is not directly rolled with lead chromium green, but the process is mixed with lead chromium green pulp to prevent burning during rolling.
Use 5
It can be used for the coloring of ceramics and enamels, rubber coloring, preparation of high-temperature coatings, fine art pigments, and preparation of ink for printing banknotes and securities. Chrome oxide green color is similar to the chlorophyll of plants, can be used for camouflage paint, can make infrared photography difficult to distinguish. It is also widely used in metallurgy, making refractory materials, grinding powder. It can also be used as a catalyst for organic synthesis and is a high-level green pigment.
Use 6
Mainly used for smelting chromium metal and chromium carbide. Used as a glaze for enamels and ceramics. Coloring agent for artificial leather, building materials, etc. It is used in the manufacture of fast coating, abrasive material, green polishing paste and special ink for printing banknotes. Used as a catalyst for organic synthesis. It's a high-grade green paint.
Use 7
Used for smelting chromium metal, chromium carbide, polishing paste and paint pigment; Also used as enamel, glass, organic and inorganic reaction catalyst, refractometric material, colored glass, abrasive.

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.
