Zirconia Ceramics: Ultra-High Performance Material Solution For Medical Devices, Precision Instruments And High-End Valves

Introduction

Zirconia ceramic (ZrO₂) is a high-performance advanced ceramic material prepared by phase transformation toughening technology. It exhibits fracture toughness close to metals, extremely high wear resistance and excellent biocompatibility. With high hardness, low friction coefficient, non-magnetic insulation, and exceptional corrosion resistance, it is an ideal choice for critical components in medical devices, precision instruments and high-end fluid control systems.

Applications

• Medical Devices: Artificial joint femoral heads, dental implants, surgical blades, orthopedic repair materials

• Precision Instruments: High-precision bearings, measuring instrument bushings, optical instrument structural parts, sensor brackets

• Industrial Valves: High-pressure valve cores, ball valve spheres, regulating valve seats, corrosion-resistant sealing rings

• Scientific Research & Semiconductors: Vacuum chamber components, wafer fixtures, insulating positioning pins, laser devices

Advantages

1. Ultra-high wear life: Hardness >1250HV, wear rate much lower than metals and other ceramic materials

2. Excellent biocompatibility: Certified according to ISO 10993, suitable for long-term implantation

3. Non-magnetic insulation and interference prevention: Does not affect precision medical equipment such as MRI, high insulation ensures system safety

4. Excellent corrosion resistance: Resists acids, alkalis, organic solvents and high-temperature steam sterilization

5. High precision and dimensional stability: Thermal expansion coefficient close to metals, enabling micron-level fit accuracy
