Chromite Powder is an oxide mineral that belongs to the spinel group. The chromite can be segregated into stainless steel, chemicals, pigments, refractories, and foundry sand. 25% of the global chromite usage share is used to manufacture chemicals, pigments (color and corrosion inhibition), and refractories. Chromite ore cannot be substituted in the production of ferrochromium, chromium chemicals, or chromite refractories. In terms of demand, the chromite powder market has been expanding due to the rise in demand for chromite in ferrochrome, chemical, refractory, and pigment industries.

THE ADVANTAGE OF CHROMITE SAND Comparing with silica sand，chromite sand can avoid most sand stick on the casting，therefor it can also save cost to make surface treatment. Moreover，chromite can be recycle used for several times upon to different technology. THE APPLICATION Chromite sand‘s’ properties enable the material to be used in high duty grey iron

Chromite sand is suitable for steel casting including foundry such as： Green Sand molding； Shell molding； Pep-Set system； Furan Resin and Alkaline-phenolic Resin； Core moulding Lost foam casting   How to Choose grit size？ Generally，the smaller casting need to make, the finer grit size foundry adopted.The following frame shows it for reference: Less than 500KGS
