Product Introduction
Brown fused alumina is a brown aluminum oxide obtained from the reduction of high quality bauxite in an electric arc furnace at a temperature greater than 2000℃.It is crushed and shaped by an automatic grinder, deferrized by magnetic separation, and sieved into various particle sizes.
Features
1.High purity. 2.Good crystallization. 3.Strong fluidity. 4.Low linear expansion coefficient and corrosion resistance.
Application
It can be used for manufacturing ceramics, resin high-consolidation abrasives, as well as grinding and polishing.
