Zirconia Ceramics: Advanced Solutions For High-Toughness, Wear-Resistant Precision Components
Introduction
Zirconia ceramic (ZrO₂) is an advanced engineering ceramic material known for its exceptional fracture toughness, high strength, and outstanding wear resistance. Through phase transformation toughening technology, it achieves mechanical properties far surpassing those of conventional ceramics. With excellent chemical stability, low thermal conductivity, and biocompatibility, it is widely used in high-precision, high-reliability, and harsh environment applications.
Applications
Precision Mechanics: Ceramic bearings, valve balls, pump seals, guide rails, precision shafts
Medical Devices: Dental implants, orthopedic joint replacements, surgical tools, medical probes
Electronics Industry: Fiber optic connectors, sensor housings, insulating substrates, piezoelectric components
Daily Consumer Goods: Watch cases, scissors blades, knife sharpeners, sporting goods
Industrial Tools: Cutting tools, grinding media, wire drawing dies, textile guides
Advantages
Highest Toughness Among Ceramics: Fracture toughness up to 10 MPa·m¹/², resistant to cracking
Excellent Wear Resistance: Surface hardness up to HV1300, ideal for friction and wear applications
Low Thermal Conductivity: Excellent thermal insulation properties, suitable for high-temperature environments
Biocompatibility: Certified biocompatible, widely used in medical implants
Acid and Alkali Resistance: Resists corrosion from most chemicals and organic solvents

Process Flow
Raw material preparation → Ball milling and mixing → Spray granulation → Mold pressing/isostatic pressing/injection molding → Pre-sintering → CNC processing → High-temperature sintering → Precision grinding → Surface polishing → Quality inspection
Usage Instructions
Avoid violent impact during installation and use, especially on thin-edged parts
When matching with metal components, consider differences in thermal expansion coefficients
Regular cleaning is recommended for components used in humid environments
Avoid prolonged exposure to temperatures above 800°C for partially stabilized zirconia
Medical implants require strict sterilization procedures before use
After-Sales Service
We provide technical consultation, application solution design, free sample testing, 12-month quality warranty, and professional failure analysis services.
FAQ
Q1: What is the difference between zirconia and alumina ceramics?
A: Zirconia offers significantly higher toughness (3-4 times that of alumina) and better wear resistance, but has lower hardness and maximum service temperature.
Q2: Can zirconia ceramics be used in food processing applications?
A: Yes, zirconia is food-safe and chemically inert, making it suitable for food processing equipment.
Q3: What are the available surface finishing options?
A: We provide grinding, polishing, and precision lapping, with surface roughness achievable up to Ra0.01μm.
