What is the true density and bulk density of white fused alumina, and what is the difference?
The density of white corundum is divided into two types, one is the bulk density of white fused alumina, and the second is the true density of white fused alumina.
Bulk density of white corundum: 1.53~1.99g/cm3,
The bulk density of the abrasive and the particle size of the abrasive are related to the “particle size composition” variety, “particle shape” and other factors. Generally speaking, the coarse-grained abrasive is finer than the coarse-grained abrasive, and the bulk density of the abrasive is larger. The bulk density is greater than the density of single particle size.
The true density of white corundum:3.95~4.0g/cm3,
the true density of the abrasive refers to the mass of the abrasive contained in the unit volume (excluding the volume of open pores).
