Alumina ceramics is a kind of Al2O3 as the main raw material, corundum (α-al2o3) as the main crystalline phase of the ceramic material, at present the world's very large amount of oxide ceramic materials. And because alumina ceramic is a very wear-resistant precision ceramic material, it is widely used in all walks of life.
Alumina ceramics have the following performance characteristics:
1. Wear resistance
High purity alumina ceramics have very good wear resistance, which is suitable for parts used for a long time.
2, no deformation
High purity alumina ceramics are excellent materials for precision parts because they have strong bending strength and compressive strength and are not easy to damage.
3, easy to clean
The surface of alumina ceramics is smooth, it is not easy to adhere to impurities, and it is easy to clean. Therefore, it is suitable for reuse and the need to maintain hygiene in the medical field.
4, chemical resistance
Alumina ceramics have strong acid and alkali resistance to chemical corrosion, and there is no need to worry about chemical reactions with other drugs during use.
5, good insulation
High purity alumina ceramic is a very good insulating material due to low impurities, it has the ability to withstand the voltage as an insulating material, low volume efficiency, even at high temperatures to maintain insulation, and excellent heat resistance.
6, plasma resistance
Due to the high purity of alumina ceramics (Al 2 O 3 > 99.9%) and has almost no intergranular segregation and, therefore, is used as an anti-plasma material.
In summary, there are some performance characteristics of alumina ceramics. Alumina ceramics have a high position in the field of ceramic materials, and are widely used in electronics, electrical appliances, machinery, textiles, aerospace and other fields.
