calcined alumina powder
1. Introduction
Alumina powder is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid washing, etc.
3. Application
1) Abrasive: Produce ceramic grinding wheel, resin grinding wheel, Grinding stone, Grinding block, sand paper, sand cloth, sand belt, polish wax, abrasive paste, coating etc..
2) Refractory material: Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy, various industrial stoves, electric furnace etc.
3) Sandblasting abrasive: Mainly used for various material workpiece to decontaminate, derusting, prevent corrosion, remove oxide skin etc..
4) Abrasion resistance ground: Mainly used for non-slip of airport and road, chemical factory
board paving.
5) Precision casting: Investment casting technical of stainless steel and alumina casting in coating.
