Yafeite White Fused Alumina

The white fused alumina is one of the complete types of abrasives manmade. The main reagent of alumina is Al2O3 (Aluminium Oxide), more than 99% roughly, and there is a small quantity of iron oxide, silicon oxide and other components.

The material is alumina powder, which undergoes smelting in the electric arc and heating at the temperatures of more than 2000℃. In the process, destruction and shaping as well as magnetic separation of the content are conducted.

White corundum or synthetic sapphire is transparent with excellent hardness. The engineered fabric can be classified in the way required for end use. The average number of the general particle size is F4~F220.

Yafeite White Fused Alumina Properties:

Along with the good of Purifying (Removal of various impurities), refractive and chemical stability, corundum, white is known for its ability to stand high temperatures, pressures and have sparkling ability. Our product is extremely tough and it has excellent corrosion resistance and grinding power.

Inter alia, the best quality white corundum has greater wear resistance and can go longer grinding operations with high intensity, it decrease wear in grinding process. Furthermore, it is thermodynamically stable at high-temperatures , nonreactive towards the other elements and has excellent corrosion resistance.

Instantly speaking about processing, we can make different shapes of the white corundum for different reasons, including spherical, the rhombus, the triangle, and so forth, and are perfect for use in different occasions.
