Plansee SE is a manufacturer of products made out of refractory metals based in Reutte, Austria.It is a wholly owned subsidiary of Plansee Group.The privately owned company was founded in 1921 by Paul Schwarzkopf and produces powder-metallurgical high-performance materials (HPM) made from metals such as molybdenum, tungsten, tantalum, niobium and chromium and their alloys.
Chromium is a chemical element; it has symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-grey, lustrous, hard, and brittle transition metal. [10] Chromium is valued for its high corrosion resistance and hardness.
Baltimore Chrome Works was a chromium ore refinery with its headquarters and main factory located at Fells Point, Baltimore, USA. Isaac Tyson started mining chromite in the area around Baltimore in 1813 and built the Baltimore Chrome Works at Fells Point in 1845.
Chromium was further enlarged with the acquisition of the chromium chemicals business of OxyChem in the US in 2002, making it the country's largest producer. This was followed by the construction of a chromium plant in China in 2004. In that same year, Elementis acquired the Dutch Sasol Servo, a supplier of coatings additives, for €48m.
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 ...
Some areas sampled had “metal-rich geologies” — hot spots for trivalent chromium; others did not. The researchers collected about 38 total soil cores from both sites that had burned and ...
In nuclear science, nuclei of heavy metals such as chromium, iron, or zinc are sometimes fired at other heavy metal targets to produce superheavy elements; [173] heavy metals are also employed as spallation targets for the production of neutrons [174] or isotopes of non-primordial elements such as astatine (using lead, bismuth, thorium, or ...
Nimonic alloys typically consist of more than 50% nickel and 20% chromium with additives such as titanium and aluminium. The main use is in gas turbine components and extremely high performance reciprocating internal combustion engines.
