Brown fused alumina/BFA/Brown Aluminium Oxide Sand 0-1-3-5-8mm Industrial Refractories Casting,Foundry and Painting
Brown corundum is made of high-quality bauxite and refined in electric arc furnace at a high temperature of more than 2000 °C. Because of its high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance, brown corundum is the best aggregate and filler for brown corundum refractories.
