It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials. Usage 1. Available research in a variety of blasting and light lapping operations 2. The process of beautifying glass or acrylic 3. The process of blasting TV screens 4. The cutting of silicon wafer 5. The process of cleaning and blasting tooth model 6. Precision sand casting 7. High refractory and other ceramic additives 8. to make sandpaper & sandcloth |
