Details

 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
