46% foundry Cr2O3 sand

foundry Cr2O3 sand

foundry Cr2O3 sand sand is an iron chromium oxide found naturally in the earth crust.It is by far the most industrially important mineral for the production of metallic chromium,used in the production of Stainless and Tool Steel. It is also used as a refractory material because of its high heat stability. The chromium extracted from foundry Cr2O3 sand is used in Chrome plating & alloying for production of corrosion resistant super alloys. foundry Cr2O3 sand is also used as a pigment for glass, glazes & paints and as an oxidizing agent for tanning leather.
