Ceramic shaft is a ceramic material with ceramics as the main body, which is used in thick film integrated circuit.ceramic shaft has good conductivity, mechanical strength and high temperature resistance.It is important to note that the need for ultrasonic washing.ceramic shaft is a widely used ceramic, because of its superior performance, in the mechanical field has been more and more widely used, to meet the needs of daily use and special performance.

1. Refractory, High Temperature Resistance, Maximum Used Temperature: 1800 ºC (3272ºF)...
2. Hardness Strength Up To Mohs 9.0; HRA 80-90, Wear Resistance wear rate 0.68 mm3·m-2·h-1....
3. High Voltage, Good Insulation Performance ,Electrical Resistivity Up To 10∧14 Ohm.Cm...
4. High Polished Surface Up To Rz0.8(Ra0.1) ...
5. Superior Mechanical Strength, Max 10 MPa.m1/2 Fracture toughness,
6. Pressure Resistance, Max 2300MPa compressive strength...
7. Anti-High Corrosion Resistance, Such As Acid  Alkali Resistance...
8. Long Service Life...
9. Other excellent property
 
After sintering, ceramic shaft material still needs finishing.Zirconia ceramic shaft parts require a high surface finish, mirror-like, to increase lubricity.Due to the high hardness of zirconia ceramic shaft material, it needs to be processed with harder abrasive polishing brick material.Such as SIC, B4C or diamond, etc.Grinding is usually carried out with coarse to fine abrasive, and the final surface is polished.
 
Ceramic parts with wear resistance, super strong, super hard, high temperature resistance (refractory), super corrosion resistance, never rust, oxidation resistance, insulation, its own lubrication and other excellent performance.
