Many people know about white corundum, which is often mentioned in life, but they know relatively little about fused white corundum. Fused white corundum is also commonly known as fused alumina. Its main raw material is calcined alumina or industrial alumina powder, which is smelted at high temperature. Its alumina content is greater than 99%. Because its raw materials are relatively pure and its chemical properties are relatively stable, almost no chemical reactions occur during electric furnace operations. Compared with ordinary white corundum, the performance of fused brown corundum has been greatly improved, such as wear resistance, high temperature resistance, hardness, etc., which have been enhanced to varying degrees. The main use of fused white corundum is to produce refractory materials, including shaped refractory materials and unshaped refractory materials. These include corundum bricks, prefabricated parts, castables, corundum porous plug bricks, etc. Fused white corundum can also be used as abrasives in various situations, such as bonded or coated abrasives, wet or dry sandblasting abrasives, grinding and polishing, etc., and can also be used as contact media, insulators, etc. All in all, the emergence of fused white corundum conforms to the development of the times and meets people's needs. It is believed that in the future, the performance of fused white corundum will be further improved and its uses will be further expanded.
