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.
