Applications of Brown Fused Alumina Refractory Grades
Brown Fused Aluminum Oxide is made from high-quality bauxite, fused with coke and iron chips at a high temperature above 2000℃. It contents 90%~97% of Al2O3 and few TiO2,SiO2 and Fe2O3. It is suitable for manufacturing vitrified and resin bonded tools, lapping, polishing and blastings, also it's widely used for making refractory materials. It's characterized with dense structure, great hardness, good self-sharpening and excellent grinding properties, low magnetic property and anti-acid corrosion.
