Brown corundum is generally used for making aggregates and fine powders in refractory materials. Its advantages are high fire resistance, wear resistance, erosion resistance, erosion resistance, large bulk density, and high alumina content. It is mainly used in high aluminum and Alumina based. There are also high load softening temperature and high temperature volume stability when making products. However, the impurities of brown corundum determine the life of the product during use. Because the impurities have not been completely removed during smelting, brown corundum also contains secondary crystal phases such as calcium hexaaluminate, anorthite, spinel, rutile, and glass phases, iron alloys, and solid solutions. In a great sense, the smelting process and smelting time of brown corundum determines its product performance and quality.
Brown corundum density:
Brown corundum density is divided into two types: one is the density of brown corundum, and the other is the particle density of brown corundum.
The bulk density is: 1.53 ~ 1.99g / cm3. The bulk density of the abrasive is related to the particle size of the abrasive, the composition of the particle size, the variety, the particle shape and other factors.
In general, coarse-grained abrasives have a higher bulk density than fine-grained abrasives, and the bulk density of mixed-grained abrasives is greater than a single particle density.
The particle density is: 3.95 ~ 4.0 / cm3. The particle density of the abrasive refers to the mass of the abrasive contained in a unit volume (excluding the volume with open pores).
