- Introduction: Used as a smelting metal chromium, chromium carbide, polishing paste and paint pigments, also used as a colorant for enamel, glass, ceramics and a catalyst for organic synthesis; used as a catalyst and analytical reagent; can be used for the coloring of ceramics and enamel, and the coloring of rubber , Preparation of high temperature resistant coatings, paints for art, for preparing inks for printing banknotes and securities. The color of chromium oxide green is similar to that of plant chlorophyll, and it can be used as camouflage paint to make it difficult to distinguish in infrared photography. It is also widely used in metallurgy, making refractory materials and grinding powder. It can also be used as an organic synthesis catalyst and is an advanced green pigment.

5. Other Information
- 5.0 Uses
- Typical properties: S.A.250m^2/gSilicon oxide is used as a catalyst support material having a high surface area. It acts as a medium to which catalyst is affixed. Several metals such as platinum, rhodium, ruthenium, silver, copper, nickel, iron, manganese, cobalt, tungsten and gold are supported over silicon dioxide and used as a catalyst in synthetic chemistry for various applications. For example, silica-supported gold catalysts is used for carbon monoxide oxidation by a solution-based technique.
