Carborundum universal ltd, a flagship company of marugappa group offers a wide range of electro minerals. As part of these products, the company offers macro grit silicon carbide. Having exceptional hardness and sharpness, it is ideally suited for grinding / sanding materials having low tensile strength like cast iron, brass, aluminum, bronze etc. Having special thermal properties, it serves as an excellent medium for use in the manufacture of refractory products and crucibles. It can also be used for polishing marble and granite. It is produced by electrochemical reaction of silica and carbon. The stoichiometric mixture is reacted in an electric arc furnace at temperatures over 2200°c to produce high quality crystals. After that the crystals are segregated, crushed, cleaned of magnetic impurities and classified into narrow size fractions for end use.
