True Density(g/cm³): ≥3.90
Key words:
White Fused Alumina
Product Description
Production process and characteristics
Using high quality alumina powder as raw material, by refining and crystallizing in electric arc furnace with high temperature. It has white color, slightly harder and lower toughness comparing with brown fused alumina. Its micro hardness is 2200-2300kg/mm². With high purity, better self-sharpening and grinding ability, good acid and caustic corrosion resistance, high temperature resistance and good thermal stability.
Applications
Refractory Grade can use for:
1. unshaped refractory products: Ladle castable, Iron runner, Gun-mix refractory;
2. shaped refractory products: Corundum bricks, Corundum mullite sagger, Three major steel making and continuous casting pieces, Ultra-temperature.
Abrasive Grade can use for:
1. Abrasives: Sand blasting, Grinding operations, Precision casting.
2. Making abrasive tools: Ceramic bonded abrasives, Resin bonded abrasives, Coated abrasives.
