WHAT IS WHITE PLATELET CALCINED ALUMINA?
White platelet calcined alumina used imported aluminum oxide as main raw material,under special treament to control the crystal grow direction and become unique flat structure.
Compare to other powder,what advantages does white platelet calcined alumina has?
First,White platelet calcined alumina has excellent overall performance,for example,high melting point,high hardness,high mechanical properties,wear-resisitance,chemical resistance,antioxidant and high temperature resistance.
Secondly,the flat shape increases the friction when grinding,then increase the grinding speed and work efficiency.in other words,it decreases the quantity of grinding machines and workers and time.
Thirdly,because of the special flat shap,the grinding object such as semicconductor silicon wafer is not easy to be scratched,qualitied product rate can be inceased 10-15%.
Fourthly,The unique flate shape makes it can combine with other active group effectively,but also easily disperse.
Fifthly,It has good adhesion,significant shielding effect and the ability to reflect light.
Sixthly,It is almost transparent,colorless,flat and smooth surface hexagonal crystals.
