High Temperature Resistance Zirconia Ceramic Technical Ceramics

1、 Introduction to Zirconia Ceramics

Zirconia ceramic is an engineering ceramic material with high performance, heat resistance, corrosion resistance, high strength, wear resistance, and good insulation properties. It has excellent mechanical, physical, chemical and other properties and is widely used in aviation, aerospace, chemical, medical and other fields.

In order to improve the performance of zirconia ceramics, different elements such as calcium and yttrium are often added, and heat treatment and preparation processes are used to adjust their properties.

2、Key Properties of Zirconia Ceramics

    I. Exceptional Toughness

      · Highest fracture toughness among oxide ceramics (6-15 MPa·m¹/²) due to stress-induced phase transformation.

      · Resists crack propagation better than alumina or silicon carbide.

   II. High Temperature Resistance

     · Stable up to 2400°F (1315°C) in fully stabilized forms (e.g., YSZ – Yttria-Stabilized Zirconia).

     · Low thermal conductivity (~2-3 W/m·K), making it ideal for thermal barriers.

   IV. Wear & Corrosion Resistance

     · Extreme hardness (1200-1400 HV) for abrasive environments.

     · Chemically inert against acids, alkalis, and molten metals.

   V. Biocompatibility

     · ISO 13356 certified for medical implants (dental crowns, hip joints).

     · No allergic reactions or toxicity in biological environments.

   VI.Electrical Properties

      · Oxygen ion conductivity at high temperatures (used in fuel cells & oxygen sensors).

      ·  Excellent insulator at room temperature.

3、Applications of Zirconia Ceramics

   （1） Medical & Dental

    - Dental crowns & bridges (aesthetic, metal-free alternative)

    - Orthopedic implants (hip/knee replacements due to biocompatibility)

    - Surgical tools (scalpels, endoscopic parts)

   （2）Industrial & Engineering

    - Cutting tools & inserts (for machining superalloys)

    - Pump seals & bearings (corrosion-resistant in chemical plants)

    - Wire drawing dies (outperforms tungsten carbide in longevity)

   （3）Electronics & Energy

    - Oxygen sensors (automotive exhaust monitoring)

    - Solid oxide fuel cell (SOFC) electrolytes (high ionic conductivity)

    - Semiconductor wafer handling (minimizes contamination)

   （4）Aerospace & Defense

    - Thermal barrier coatings (TBCs) for jet engine turbines

    - Armor plates (lightweight, bulletproof composites)

Conclusion: Zirconia ceramics are a versatile high-performance technical ceramic, bridging the gap between metals and traditional ceramics. 

Their unmatched combination of strength, thermal resistance, and biocompatibility ensures growing adoption in cutting-edge industries.

﹡Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
