High Purity Alumina Powder
                 

9.jpg

99.99% series high purity Al2O3,which mainly applied in the HPSL (high pressure sodium lamp) pipe material, LED synthetic sapphire crystal, advanced luminescent materials, special ceramics, advanced coating, three primary colors, catalyst and as well as some high performance material etc. As raw material of sapphire crystal, the powder can be processed to become granular (mm grade) or agglomerate by the customer’s request.

 

Property:

1. Phase stable, hardness, superfine particle size and homogeneous distribution;

2. Strong grinding force, fast polishing, high efficiency, light luminosity and mirror effect;

3. High-efficiency milling result, good polishing effect, the mill efficiency is higher than the soft abrasive like SiO2, the surface smoothness is better than the polishing effect of the white alundum, strong cutting force, quick polishing, clarity, and efficiency.
