Chromite sand is a naturally occuring spinel consisting primarily of the oxides of chrome and iron after crushing, grinding and sieving. We import crushing Chrome ore from South Africa, wash, dry, dust cleaning, grinding, sieve and pack in China port, then export to all over the world directly, and its main chemical composition is Cr2O3. Chromite powder has good thermal conductivity, good resistance to thermal shock, excellent resistance to metal penetration or burn-on, resists slag attack and high dimensional stability.
