Foundry Grade Chromite sand is a complex compound of various elements. The main elements Chromium as Cr2O3, Aluminium as Al2O3, Silica as SiO2, Magnesium oxide as MgO. It is a lustrous, brittle, hard metal. Its colour is silver-grey and can be highly polished. It does not tarnish in air, when heated it burns and forms the green chromic oxide.
