Chromium(II) carbide is a ceramic compound that exists in several chemical compositions: Cr 3 C 2, Cr 7 C 3, and Cr 23 C 6.At standard conditions it exists as a gray solid. It is extremely hard and corrosion resistant. It is also a refractory compound, which means that it retains its strength at high temperatures as well. These properties make it useful as an additive to metal alloys.
Global Tungsten & Powders (GTP) develops, manufactures and markets refractory metal powders such as tungsten, tungsten carbide, molybdenum, and cobalt. GTP is a leading Western supplier with production facilities in the United States, Finland, and the Czech Republic. Think Tungsten. Think GTP.

Tungsten and Tungsten Wire History Sheelite. The word “Tungsten” was probably first used by A. F. Cronstedt in 1755, who applied it to the mineral subsequently known as “scheelite,” which is the natural form of calcium tungstate.C. C. Leonhard named this mineral scheelite in 1821 in recognition of the discovery made by K. W. Scheele, in 1781, that the mineral was a compound of lime
