Chromium deficiency is described as the consequence of an insufficient dietary intake of the mineral chromium. Chromium was first proposed as an essential element for normal glucose metabolism in 1959, [ 1] but its biological function has not been identified. [ 2] Cases of deficiency were described in people who received all of their nutrition ...
Chromium (IV) oxide (CrO 2) is a magnetic compound. Its ideal shape anisotropy, which imparts high coercivity and remnant magnetization, made it a compound superior to γ-Fe 2 O 3. Chromium (IV) oxide is used to manufacture magnetic tape used in high-performance audio tape and standard audio cassettes.
Low-molecular-weight chromium-binding substance ( LMWCr; also known as chromodulin) is an oligopeptide that seems to transport chromium in the body. [1] It consists of four amino acid residues; aspartate, cysteine, glutamate, and glycine, bonded with four (Cr 3+) centers. It interacts with the insulin receptor, by prolonging kinase activity ...
Chromium dioxide or chromium (IV) oxide is an inorganic compound with the formula CrO 2. It is a black synthetic magnetic solid. [3] It once was widely used in magnetic tape emulsion. [4] With the increasing popularity of CDs and DVDs, the use of chromium (IV) oxide has declined. However, it is still used in data tape applications for ...
Ferrochrome or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight. [1] [2] Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic ...
Chromium trioxide (also known as chromium (VI) oxide or chromic anhydride) is an inorganic compound with the formula CrO3. It is the acidic anhydride of chromic acid, and is sometimes marketed under the same name. [6] This compound is a dark-purple solid under anhydrous conditions and bright orange when wet.
Hexavalent chromium. Hexavalent chromium ( chromium (VI), Cr (VI), chromium 6) is any chemical compound that contains the element 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]
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]
