Zirconia Ceramics: Ultra-High Performance Material Solution For Medical Devices, Precision Instruments And High-End Valves
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
Ultra-high wear life: Hardness >1250HV, wear rate much lower than metals and other ceramic materials
Excellent biocompatibility: Certified according to ISO 10993, suitable for long-term implantation
Non-magnetic insulation and interference prevention: Does not affect precision medical equipment such as MRI, high insulation ensures system safety
Excellent corrosion resistance: Resists acids, alkalis, organic solvents and high-temperature steam sterilization
High precision and dimensional stability: Thermal expansion coefficient close to metals, enabling micron-level fit accuracy

Process Flow
Nanoscale powder preparation → Stabilizer doping → Spray granulation → Isostatic pressing → Pre-sintering → CNC engraving → High-temperature sintering → Centerless grinding → Laser marking → Plasma cleaning → Full inspection packaging
Medical implants should be unpacked in a sterile environment and installed with special tools
When matching with metals, transition fit is recommended, avoid interference exceeding 0.01mm
Regularly check wear condition, professional inspection recommended every 1000 working hours
Do not use hydrofluoric acid cleaners, ultrasonic pure water cleaning is recommended
Provide material certification reports, process validation data, free technical training, 24-month quality traceability for medical products, 12-month extended warranty for industrial products
Q1: Does zirconia ceramic undergo aging in medical applications?
A: Using the latest third-generation yttria-stabilized zirconia, passed low-temperature degradation (LTD) testing, service life exceeds 20 years
Q2: Can it meet FDA and CE certification requirements?
A: All medical grade products have passed FDA 510(k) and CE Class III certification, providing complete technical documentation
Q3: Is microporous structure processing supported?
A: Supports processing of microholes above 0.1mm, accuracy up to ±0.002mm, with internal surface polishing treatment
