Introduction
Brown Fused Alumina is obtained from a mixture of high quality bauxite, coal and iron scrap in an electric arc furnace at high temperature. Its thermal properties make it an excellent material for use in the manufacturing of refractory products. Brown Fused Alumina is a tough, hard material with high strength, excellent wear and corrosion resistance and good thermal conductivity.
