THE QUALITY OF PLATELET ALUMINUM OXIDE FROM CHINA
Platelet aluminum oxide is a specifial aluminum oxite with platelet shape.
Recent years, the platelet aluminum oxide researched and made from national manufacturers has been highly recognized during grinding semiconductor and single silicon wafer.
The crystal thickness of china platelet aluminum oxide is about 1-2microns and diameter is 2-50microns.
Besides,it has lower Na2o and higher Al2O3,and with specifial hexagonal sheet structure,which avoid scratching the finished surface.
Compare with PWA from Japan Fujimi and WCA from USA Microgrit,can not say they are same,just can say they are similiar.
The most important factor is that the unit price of platelet aluminum oxide from China is relatively lower.
