Brown corundum is used in refractory materials and its density


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 for high aluminum and Alumina based. It also has high 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, and rutile, as well as 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:
There are two types of brown corundum density: one is the bulk 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, composition, variety, particle shape and other factors of the abrasive.
Generally speaking, 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).
