Zirconia Ceramic Shaped Parts Product Introduction:
Zirconia ceramic shaped parts refer to non-standard components made primarily from zirconia (ZrO₂), custom-manufactured according to customer-provided drawings. They possess the following significant characteristics:
1. High Hardness and Wear Resistance: Rockwell hardness HRA 78-90, Mohs hardness 6.5-9, second only to diamond, with wear resistance 266 times that of manganese steel.
2. Excellent Toughness: Fracture toughness reaches 1-35 MPa·m¹/², making them more impact-resistant than ordinary ceramics.
3. High Temperature Resistance: Melting point up to 2715-2850℃, maintaining stability in high-temperature environments.
4. Chemical Stability: Corrosion-resistant and oxidation-resistant, suitable for harsh chemical environments.
5. Biocompatibility: Widely used in the medical field, with good affinity to human tissue.
Manufacturing Process
1. Powder Preparation: High-purity zirconia powder is prepared using the co-precipitation method or hydrothermal synthesis method.
2. Precision Machining: Grinding, polishing, and laser processing are used to achieve an accuracy of ±0.001 mm.
