Chromite sand. Apply for glass industry
Chromite sand. Apply for glass industry. Cr2O3 = 43-47% Grain size =200 mesh is a product of south africa natural chromite ore after crushing and sieving. We import crushing Chrome ore from South Africa, wash, dry, dust cleaning, sieve and pack in China port, then export to all over the world directly, and its main chemical composition is Cr2O3. Chromite sand has good thermal conductivity, good resistance to thermal shock, excellent resistance to metal penetration or burn-on, resists slag attack and high dimensional stability.
