shenxing ceramic heating resistance 95% alumina ceramic insulator for ignitor electrode
Alumina Ceramic Advantages
1). Strong acid resistance
2). Strong insulation
3). Strong adsorption
4). High thermal insulation performance
5). Chemical stability
6). High compressive strength
Alumina Ceramics have a high melting point, high hardness,although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. So it is widely used for many mechanical parts which request very high temperature.
