White Fused Alumina is produced by the high Quality alumina by melting above 2000 in th electric arc furnance and cooling, It is also characterized by its high purity, ability of self-sharping, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability.
Applications
1,Used for lapping and polishing ,non-slid tile, pressure blasting when a high purity and highly friable abrasive is needed.
2,Used as refractory materials
3,Applied to abrasive tools
