Quality Brown Fused Alumina, Silicon Carbide, Ceramic …
Brown Fused Alumina Brown fused aluminum oxide (Al2O3) is also known as brown fused alumina, which is produced by the smelting of calcined bauxite in an electric arc furnace. It is a hard and tough material with high strength, excellent wear resistance and good thermal conductivity.
Products - IMEXCO
Since the beginning of the 20th century, fused alumina are synthetically produced. Synthetic fused alumina is formed by fusion in an electric arc furnace at temperatures of over 2,000 °C. Fused alumina is produced in different ways depending upon the input raw materials (bauxite, calcined alumina) and the use of further additives.

Brown Fused Alumina is a product manufactured by gradual melting reduction of calcined bauxite in an electric arc furnace at high temperature (approximately 2000 degrees Celsius). Its chemical composition consists mainly of Al2O3 (94.5-97%) and vestigial amounts of TiO2, SiO2, Fe2O3, CaO and MgO.
Brown Fused Alumina - Exporter-Domill Abrasives
Brown fused aluminum oxide is a tough, hard material (Mohs hardness 9) with high strength, excellent wear and corrosion resistance and good thermal conductivity. Fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other appliions.
Foundry - CUMI EMD Synthetic Fused Alumina | White …
CUMI’s synthetic fused alumina produced by controlled fusion of special alumina with other raw materials ensure low bulk density (1.7 vs 2.9 g/cc) and high refractoriness (PCE of 18500C +). This material exhibits very low thermal expansion coefficient (7.2x 10-6 / 0 C) which makes it a perfect substitute for zircon sand in foundry appliion.
