Chromite sand/powder/flour
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.
Chrome powder/flour is ground from chromite sand,mainly used for ceramic glaze,glass/ink pigment,refractory bricks,cement and coating etc.
