Brown Fused Aluminum Oxide: An Overview
Brown fused aluminum oxide , also known as brown fused alumina (BFA) or brown corundum, is a synthetic abrasive material made from the fusion of high-quality bauxite, coke, and iron filings in an electric arc furnace at high temperatures. It is a tough, durable, and hard-wearing material widely used in a variety of industries, including the abrasives, refractories, and surface finishing sectors. Properties of Brown Fused Aluminum Oxide Brown fused aluminum oxide is characterized by its high hardness (9 on the Mohs scale), high melting point (2050°C), and chemical stability. It has excellent thermal conductivity, high electrical resistivity, and a low coefficient of thermal expansion. These properties make it an ideal material for various applications requiring high-performance abrasives and refractories. Production Process of Brown Fused Aluminum Oxide Raw Materials The primary raw materials for producing brown fused aluminum oxide are calcined bauxite, coke, and iron filings. Calcined...
