Chromite - Wikipedia

Chromite can be used as a refractory material, because it has a high heat stability. 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. It is also sometimes used as a gemstone. Usually known as chrome, it is a very essential industrial metal. It is hard and resistant to corrosion. Thi…
