Chromite sand products add color and provide functional properties essential to tint glass and ceramics or improve the performance of foundry castings, friction of brake pads and weight of drilling fluids.
PRODUCT:CHROMITE SAND
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.
