Advantages of alumina ceramic pieces
Time：
2023-05-16
Alumina ceramics are ceramic materials with Al2O3 as the main raw material and corundum (a-Al2O3) as the main crystalline phase. Alumina ceramics are usually sintered at a higher temperature because the melting point of alumina is as high as 2050℃. Therefore, the production of alumina ceramics requires the use of high temperature heaters or high-quality fuels as well as high-grade refractory materials as kilns and furnaces, which to some extent limits their production and widespread application. So what are the advantages?
Alumina ceramics have the advantages of high mechanical strength, high hardness, low high-frequency dielectric loss, because of its wide source of raw materials, relatively low price, mature processing technology, is widely used in electronics, electrical appliances, machinery, textile, aerospace and other fields. In the field of ceramic materials also established a higher position. It is reported that alumina ceramics are widely used oxide ceramics in the world.
