White aluminum oxide is made of high-quality alumina powder. The processing technology of high-temperature calcined alumina powder and white aluminum oxide is different, and the results are also different. So what are the differences between white aluminum oxide and calcined alumina powder?
High-temperature calcined alumina powder is processed by 1300-1400℃ roasting in a rotary kiln. It has high temperature resistance and wear resistance, so it is mostly used in refractory and ceramic industries. White aluminum oxide is made by melting at a high temperature of more than 2000 degrees in an arc and then cooling down. It is crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes. Because white aluminum oxide has dense crystals, high hardness, and sharp-angled particles, it is suitable for manufacturing ceramics, mold abrasives, polishing, sandblasting, etc. It can also be used to manufacture refractory materials. It is a very important abrasive.
High-temperature calcined alumina powder is relatively easy to process and has low processing costs, so it is widely used in refractory and ceramic industries. It meets customer needs while reducing production costs. Finely 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, porcelain tubes and other high-temperature materials, high-frequency insulating ceramics, LCD substrate glass, etc.
It can be seen that alumina powder and white aluminum oxide have their own characteristics.
