What is the density of white fused alumina

White fused alumina is one of the most commonly used abrasives, especially in the sandblasting industry, mainly for surface beautification pre-processing, burr processing, stress relief processing and so on. So what is the density of white fused alumina? The editor of white fused alumina manufacturers will share the knowledge about the density of white fused alumina.White fused alumina is the main raw material for fire brick.

The crystals of white fused alumina are white, with high-quality alumina as the raw material, the content of AI2O3 is greater than 98.5%, and the hardness is high, but the toughness is not as good as that of brown fused alumina. The content of Fe2O3 in white fused alumina is very low, which is suitable for sandblasting operations where iron residues are strictly prohibited.

The material of white fused alumina is relatively hard, suitable for most sandblasting machines, and also used as grinding and polishing materials, sand for precision casting, spraying materials, chemical catalyst carriers, functional ceramics, refractory materials, etc.
The density of white fused alumina is divided into two types, one is the bulk density of white fused alumina, and the other is the true density of white fused alumina. The bulk density is 1.5~1.99g/cm3. The bulk density of the abrasive is related to the particle size, particle size composition, variety, particle shape and other factors. Generally speaking, the bulk density of coarse-grained abrasives is higher than that of fine-grained abrasives. The bulk density is greater than the density of a single particle size. The particle density is 3.95~4.0g/cm3.
