Alumina ceramic is a ceramic material based on aluminum oxide (Al2O3) and is used in thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramic is a widely used ceramic. Because of its superior properties, its application in modern society has become more and more extensive, meeting the needs of daily use and special properties.
1.High temperature resistance, Pure alumina ceramics are ceramic materials with an Al2O3 content of more than 99.9%. Due to their high sintering temperature of 1650-1990ºC.
2.High strength and excellent hardness.
3.Good Corrosion and Oxidization resistance.
4.Tight tolerance and good surface roughness.
