As a compound, it has varied and robust colors. Chromium ion forms many coordination compounds. In active and passive forms, the latter gives rise to its corrosion resistance due to a thin surface oxide layer that passivates the metal when treated with oxidizing agents. Synonym: Chromium dichloride, Chromous chloride Linear Formula: CrCl 2.

Chromium metal is a chemical element by the symbol Cr and atomic number 24. It is the first element in group 6. Chromium is the principal additive in stainless steel, to which it adds anti-corrosive properties. Chromium is also highly valued as a metal that is capable to be highly polished while resisting tarnishing.

302 ( k ) Ferrochrome or ferrochromium containing less than 3 per centum of carbon , and chrome metal or chromium metal Muck bars , pieces thereof except 

It is a hard, corrosion-resistant transition metal. Chrome, which you may see as decorative trim on cars and motorcycles or to harden tools used for industrial processes, is an electroplated layer of chromium over another metal. Either hexavalent chromium or trivalent chromium may be used to produce chrome.

Chromium metal is primarily used for its ability to help steel resist corrosion and increase hardness. What we commonly refer to as stainless steel is actually composed of over 13.5 percent chromium. The metal can be produced using three methods: (1) an aluminothermic process, (2) a silicothermic process, or (3), an electrolytic process.

Chromium steel, which resists warping or melting under conditions of extreme heat, is ideal for high-temperature applications such as jet-engine components. The principle chromium ore, chromite, is heat resistant in the same way. It is this property, along with its chemical stability, that makes chromium useful as a refractory material. In its elemental form, chromium has a lustrous steel-gray appearance. Chromium is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it tranforms into a paramagnetic solid. The most common source of chromium is chromite ore (FeCr 2 O 4).
