CAS: 7440-47-3 Molecular weight: 52
Description: Chromium is a silvery white lustrous metal. Pure chromium has ductility. Chromium containing impurities is hard and brittle, and soluble in strong alkali solution. Chromium has a high corrosion resistance, and oxidation is slow in the air, even in the state of red heat. Insoluble in water. Plated on metal for protection. Ferrochrome and silicochromium, widely used in iron and steel industry, are smelted in electric furnace. In the production of chromium, the methods of thermite reduction and electrolysis are used. Aluminothermic production includes two processes: the production of chromium oxide from chromite and the production of metal chromium from aluminum reduction chromium oxide. Generally, carbon ferrochrome is used as raw material in electrolytic production, and chrome ammonium alum method is used for electrolysis.

Used: High purity metal chromium is used to make optical coating materials and chromium targets. Chromium is mainly used to produce stainless steel and various alloy steels in the form of ferrochromium. Chromium is used as additive of aluminum alloy, cobalt alloy, titanium alloy, high temperature alloy and resistance heating alloy. Chrome plating and chromizing can make steel, copper, aluminum and other metals form a corrosion-resistant surface layer, which is bright and beautiful, and widely used in furniture, automobile, construction and other industries. In addition, chromite is also widely used to make refractories.
