White fused aluminum oxide is produced by fusing alumina block in an electric arc furnace under carefully controlled conditions. The material produced is white in color, dense and has predominantly large crystals of Alpha Alumina. Ingots are crushed, ground, and precision screened in our new sizing plant to obtain very consistent sized fractions. Magnetic iron from crushing is removed by rare earth magnets to ensure very low levels of iron in the finished products. Close sized fractions are available or precision blended to specification. This process ensures a very consistent sizing from coarse to fines which is critical in many applications
The physical and chemical analysis:
Size: JIS2500#

***ails:
1. High hardness, particle density, good single particle roundness;
2. White, no impurities, ensuring wear-resistant layer or wear on paper color and tran***rency;
3. Particle size distribution concentrated, single single-particle form, minimum amount with maximum effect
4. Selected from the melting temperature by more than 2000 degrees well made of quality white fused alumina as raw material, its chemical stability and acid and alkali effect does not occur, small shrinking
