In the precise surface polishing field with a flat honing or double sides lapping machine, the white fused aluminum oxide powder is a widely used abrasive powder.

For some precise components such as Monocrystalline silicon wafer, metal and stainless steel component. The aluminum oxide powder is an ideal choice to make polishing liquid and polishing compounds. That is because fused Al2O3 is of high hardness up to Mohs 9.0 and good grinding ability.

There is a key factor to adopt proper aluminum oxide powder: particle size distribution. To avoid scratches on the component surface, it has to get even PSD powder. Big micro-grain in the powder will hurt the surface and hard to repair. That will cause irreversible results for the polishing and lapping work.

The sieving process of white aluminum oxide polishing powder from HAIXU Abrasives is water sieving. In the meantime, the production process is under monitoring by experienced technicians. Our engineers know exactly how to control the whole production to get different sizes of powder even with 1 micron/1.5microns/2.5microns/3.5 microns.

After that, we will test the powder with Laser particle size analyzer equipment. Once the PSD diagram gets a smooth curved line, it will meet the demand of lapping and polishing. Thus it will help users to get a good effect on polishing.
