Chrome Sand is often used in the moulds for automotive castings, like engine blocks and camshafts, but it is preferred for many other foundry uses because of its resilient characteristics. Chrome Sand is also used as a primary material in the production of green glass, in well fillers, and to augment the refractory fire brick

chromite sand is used in the foundry industry as a moulding sand, as a pigment in ceramic glazes and container glass, and as an additive in brake lining applications. Chromite sand is characterised by: high melting point excellent thermal stability high density medium Mohs hardness of 5.5  CHEMICAL COMPOSITION Cr2O3 ≥46.0% SiO2 ≤1.0% FeO ≤26.5%
