High-temperature calcined alumina powder and white corundum are both processed from industrial-grade alumina, but the processing techniques of these two substances are quite different. High temperature calcined alumina powder adopts rotary kiln, the roasting temperature is around 1300-1400 ℃, and has the characteristics of high temperature resistance and wear resistance, so calcined alumina is generally used in the ceramic industry, abrasives, refractory materials, fillers and other industries.
Precisely produced calcined alumina powder can also be used in electronic vacuum tube shells, spark plugs and other electronic ceramics, sealing rings, textile machinery and other wear-resistant ceramics, alumina crucibles, ceramic tubes and other high-temperature materials, high-frequency insulating ceramics, LCD substrate glass, etc.
Yufa Fine Ceramics Technology Co., Ltd., a subsidiary of Zhengzhou Yufa Abrasives Group, has been producing high-quality low-sodium calcined alumina for more than 20 years.
White corundum is made of electric arc, which needs to be smelted at a high temperature of more than 2000 degrees and then cooled. At the same time, because of its dense crystal and high hardness, white corundum is widely used in refractory materials, mold abrasives, polishing, etc.
Compared with white corundum, ordinary high temperature calcined alumina is relatively less difficult to process, and the processing cost is lower, so it is widely used in the refractory and ceramic industries.
