Brown Fused Alumina uses high-quality bauxite, iron filings, and anthracite as raw materials, and is smelted at a high temperature in an electric arc furnace to exceed 2000℃. The brown corundum section sand is obtained by crushing the original slab of brown corundum, magnetic separation, and sieving. Brown fused alumina has the characteristics of high purity, good crystal fluidity, low linear expansion coefficient, corrosion resistance, high-temperature resistance, and high strength. It is suitable for grinding, polishing, sandblasting, precision casting, etc., for refractory materials.
