Properties: White aluminium oxide is manufactured from aluminium oxide smelted at high temperature,white,acid and alkali resistant,corrosion resistant,with high hardness mosh 9. Compared with brown fused alumina, it is of higher hardness and slight lower toughness.

It is also characterized by its high purity, ability of self-sharpening, high cutting rate, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability.It is available for grinding,polishing,precision casting,coating,chemical media,special ceramics and refractory materials etc.In addition,the EFA micropowder has a good insulation,suitable for crystal,electronic industry ultra-fine griding,polishing and production of high-grade refractory.

Application:

White fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media,metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.

White fused alumina grains and powders are available in standard mesh, they can also be made to individual specifications.
