Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.
Chromite sand has the following physical and chemical properties:-
Melting point of 2150°C
Good thermal conductivity
Good resistance to thermal shock
Excellent resistance to metal penetration or burn-on
Resists slag attack
High dimensional stability
