Description of White Fused Alumina Powder
White fused alumina is a kind of high-grade refractories material. It was made in high quality Alumina by melting above 2000℃ in electric arcfurnace.The molten material undergoes cooling, crushing, grinding, sieving,
classifying and, of course, various quality checking procedure before it is packed
for delivery. It has the advantages of high purity Al2O3>99.3%,good polishing effect: brightness, no scratch,strong grinding ability,high hardness.
Usage:
1. Precision sand casting
2. The cutting of silicon wafer
3.The process of blasting TV screens
4.The process of beautifying glass or acrylic
5.High refractory and other ceramic additives
6. The process of cleaning and blasting tooth model, light lapping operations
