Industry Applications

1. Medical & Dental Implants

Surgical guide blocks & dental abutments (biocompatible, ASTM F1873 compliant)

2. Industrial Wear Components

Pump seals, bearing races – Outlasts tungsten carbide in slurry environments

3. Semiconductor & Electronics

Plasma-resistant chamber liners – Zero particle contamination in etching tools

4. Automotive Sensors

Oxygen sensor substrates – Thermal shock-resistant λ-probe cores

5. Precision Machinery

Laser cutting nozzles – Withstand abrasive particle erosion

Why Choose Zirconia Blocks?

✔ Superior Toughness – 6–8 MPa·m¹/² fracture toughness (vs. 3–4 for alumina)

✔ Metal-Matching CTE – Enables thermal cycling stability in bonded assemblies

✔ Custom Fabrication – CNC/Laser machining to ±0.01mm tolerances

✔ Surface Finishes – Polished (Ra <0.05µm) or as-sintered (Ra 0.2µm)

Ceramic Properties

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
