Many users do not know the difference between high-temperature alumina and alumina, and some even mix the two together, in order to facilitate the purchase of suitable alumina, please spend two minutes to look at our article.
Alumina melting point of about 2000 degrees, is a white solid insoluble in water, tasteless, hard texture, easy to absorb moisture but not deliquescence, belongs to the amphoteric oxide, can be dissolved in inorganic acids and alkaline solutions, almost insoluble in water and non-polar organic solvents, high temperature resistance, can be used as refractory materials.
High-temperature alumina is calcined at high temperatures and is resistant to acid and alkali corrosion, high temperatures, high strength and hardness, and can be used for durable materials.
Alumina ceramics are divided into high purity type and ordinary type. High purity type refers to ceramic materials with Al2O3 content of 99.9% or more. Ordinary type is the Al2O3 content is divided into 99 alumina ceramics, 95 alumina ceramics, 90 alumina ceramics, 85 alumina ceramics and other varieties, sometimes the Al2O3 content of 80% or 75% is also classified as ordinary alumina ceramic series.
99 alumina ceramics high temperature resistance performance, 99 alumina porcelain materials can be used to make high temperature crucible, refractory furnace tube and special wear-resistant materials, such as Ceramic bearings, ceramic seals and water valve pieces, etc. When you want to use high temperature resistance, 99% alumina ceramic is the best choice.
Alumina ceramics are more widely used in electronic appliances, military research and other industries because they still have excellent insulation properties at 1000°C. And alumina ceramics can ensure that it has excellent insulation properties, but also have wear resistance, high temperature resistance and other properties, so more and more industries are beginning to use alumina ceramic materials to replace the traditional plastic material parts.
