Chromite
Chromite is used extensively as a refractory material. It is used in the manufacture of refractory brick, basic brick, foundry 'sand', castables, mortar, and ramming and gunning compounds. Chromite has a high melting temperature range of 1545 to 173O⁰C, depending on its composition, making it a desirable component in refractory brick in ferrous and nonferrous furnaces.
