Brown Aluminum Oxide
Brown fused alumina (BFA), also known as silicon carbide, is smelted in an electric arc furnace from three raw materials: alumina, carbon, and scrap iron. Therefore, the main chemical composition of brown fused alumina is AL2O3, and its content is 95.00% to 97.00%. , and also contains a small amount of Fe, Si, Ti.
Over View Brown Fused Alumina Oxide
Brown corundum is the most basic abrasive, with good grinding performance, wide applicability, and low price. It is suitable for grinding high-strength metals, such as various ordinary steel, malleable cast iron, hard bronze, etc. It can manufacture advanced refractory materials. Brown corundum has high purity, good crystallinity, strong fluidity, low linear expansion coefficient and corrosion resistance.
