Jadeite refractory raw materials and their classification2024-10-15Corundum is a polycrystalline alpha alumina material. Aluminum oxide is one of the main components of the Earth's crust, with the advantages of abundant resources and relatively inexpensive availability. Corundum has physical and chemical properties such as high temperature resistance, high strength, high hardness, electrical insulation, and corrosion resistance. As a result, corundum has become a widely used refractory material.- Detailed introduction to the raw material for producing corundum: bauxite2024-10-15So far, the production of corundum mainly uses two types of raw materials: one is to directly melt or sinter natural bauxite into brown corundum, alumina corundum, sub white corundum, etc; Another method is to use industrial alumina for electric melting or sintering into white corundum, dense corundum, plate-like corundum, sintered corundum, etc. More than 95% of industrial alumina is extracted from bauxite. It can be seen that bauxite is an important raw material for producing corundum. Aluminu
- What are the main uses of corundum in refractory materials2024-10-15Due to the abundant raw materials used and convenient supply of corundum materials, they can be used in the production process of traditional refractory materials to produce corundum refractory materials, as well as in the production of special refractory materials, namely high-temperature ceramics, using methods derived from traditional ceramics. Therefore, after more than half a century of research and production, the process has become increasingly mature and the variety has continued to incr
