Introduction of White Fused Alumina Technology

White fused alumina is made of high quality aluminum oxide powder which is taken as the raw material by the fusion of aluminum oxide powder in an electric arc furnace under high temperature of more than 2000 degrees. It has many advantages, such as high purity, good self-sharpening, great acid and alkali resistance, high temperature resistance, stable thermal state performance, and its hardness is slightly higher than that of brown fused alumina. Although its toughness is a bit low, but its purity is good. What’s more, it has high grinding ability, low calorific value, high efficiency and so on. 

Abrasives products made by white fused alumina are suitable for manufacturing ceramic porcelain, resin consolidation abrasive, grinding, polishing, sandblasting, precision casting (precision casting special corundum), etc., and it can also be used for manufacturing high-grade refractory materials.

White fused alumina is a kind of artificial abrasive and aluminum oxide (Al₂O₃) accounts for over 99% of white fused alumina, with a small amount of ferric oxide, silicon oxide and other components. It is showed in white.

The product particle size of white fused alumina can be produced according to the international standard and national standard and is also processed according to user requirement for granularity, whose universal particle size is from F4 to F220 and chemical composition can depend on the size of the particle size. The outstanding characteristic is that the crystal size is small with impact resistance. if using autogenous grinding machine to process, the grains are mostly spherical particles whose surface is dry and clean, easy to bond.

The bulk density of white fused alumina:

1.53 ~ 1.99g/cm3, the bulk density of abrasive is related with the particle size of abrasive, the composition and varieties of particle size and other factors. In general, the coarse-grained abrasive has higher bulk density than the fine-grained abrasive, and the bulk density of mixed granularity abrasive is greater than that of single particle.

The true density of white fused alumina:

3.95 ~ 4.0g/cm3, the true density of abrasive refers to containing quality of the abrasive in the unit volume of abrasive (excluding the open pore volume).

The fundamental granularity of white fused alumina:

45% ~ 55%, and the fundamental granularity is the important indicator to ensure the grinding effect and can be properly controlled in the production, but the production speed may need to keep slow.
