Introduction of two densities of white corundum?
White corundum is made of industrial alumina powder, which is smelted at a high temperature above 2000 degrees in an electric arc and then cooled. After crushing and shaping, magnetic separation to remove iron, and screening into various particle sizes, the texture is dense, the hardness is high, and the particles form sharp corners. It is suitable for the manufacture of ceramics, resin-bonded abrasives, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc., and can also be used to manufacture advanced refractory materials. The density of white corundum is divided into two types,
One is the bulk density of white corundum, and the other is the true density of white corundum. The bulk density is: 1.53–1.99g/cm3. The bulk density of the abrasive is related to the particle size, particle size composition, variety, particle shape and other factors of the abrasive. Generally speaking, the bulk density of the coarse-grained abrasive is higher than that of the fine-grained abrasive. The bulk density of the abrasive is greater than the single particle size density.
True density: 3.95~4.0g/cm3,
