Electric isolator / ceramic / DC / alumina

Alumina is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.

During the prodcution, small amounts of silica (SiO2), magnesia (MgO) and zirconia (ZrO2) may be added to alumina ceramics. The applications vary with the purity of Alumina. 99% Alumina Ceramics are mostly used for high temperature crucibles, kiln furniture, special abrasion resistant parts, such as ceramic bearings, ceramic sealings or faucet discs; 95% Alumina Ceramics are usually applied for corrosion-resitant components or wear proof parts; 85% Alumina Ceramis can be metallized with metals like molybdenum, niobium, tantalum to use for electric vacuum devices.

Applications:
1. Seal rings
2. Medical prostheses
3. Laser tubes
4. Electronic substrates
5. Ballistic armour
6. Thermocouple tubes
7. Electrical insulators
8. Grinding media
9. Threadguides
10. Wear components
