Aluminum oxide ceramics applications
Alumina ceramics are the most common advanced ceramic material and more traditional. As an excellent ceramic material, high purity alumina ceramics have been widely used in many industries. The material has excellent properties in terms of electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion. Therefore, alumina ceramic products are ideal for many industries such as:
- Shafts and plungers in high wear environments
- Roller and ball bearings
- Wear-resistant lining
- semiconductor part
- Machine components
- High temperature electrical insulators
- High-voltage insulators
- Wires and conductors
- mechanical seal
Basic Properties of Alumina Ceramics
