Material

Superfine Al2O3 powder, 99.95%

 

Specification

 

 

alpha phase (corundum), 99.95%, superfine powders, suitable for fast and smooth final stages polishing.  Much faster polishing rate than silica due to higher hardness.  Much less scratches comparing with SiC or fused Al2O3 due to smooth particle morphology.

m.p. 2045 oC, b.p. 2980 oC, density 3.97 g/cm3
