2. Chromium - Wikipedia

   en.wikipedia.org/wiki/Chromium

   The two main products of chromium ore refining are ferrochromium and metallic chromium. For those products the ore smelter process differs considerably. For the production of ferrochromium, the chromite ore (FeCr 2 O 4) is reduced in large scale in electric arc furnace or in smaller smelters with either aluminium or silicon in an aluminothermic ...

3. Hexavalent chromium - Wikipedia

   en.wikipedia.org/wiki/Hexavalent_chromium

   Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is any chemical compound that contains the element chromium in the +6 oxidation state (thus hexavalent). [1] It has been identified as carcinogenic, which is of concern since approximately 136,000 tonnes (150,000 tons) of hexavalent chromium were produced in 1985. [ 2 ]

   This is a list of countries by chromium ore production in 2023, based on the United States Geological Survey. [1] Chromium is a chemical element that is designated by the symbol Cr and has an atomic number of 24. It is usually found as the mineral chromite, from which ferrochrome is produced in a smelting process.

5. Chromium compounds - Wikipedia

   en.wikipedia.org/wiki/Chromium_compounds

   Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals. The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist. [3] [4]

   Chromium is a free and open-source web browser project, primarily developed and maintained by Google. [3] It is a widely-used codebase , providing the vast majority of code for Google Chrome and many other browsers, including Microsoft Edge , Samsung Internet , and Opera .

7. Chromite - Wikipedia

   en.wikipedia.org/wiki/Chromite

   The chromium extracted from chromite is used in chrome plating and alloying for production of corrosion resistant superalloys, nichrome, and stainless steel. Chromium is used as a pigment for glass, glazes, and paint, and as an oxidizing agent for tanning leather. [27] It is also sometimes used as a gemstone. [28]
