Product Introduction

Product Overview

Our 99% Al₂O₃ ceramic rods, shafts, and sticks are precision-engineered for applications requiring exceptional thermal stability, wear resistance, and electrical insulation. These high-performance linear components withstand continuous operation at temperatures up to 1600°C (2912°F) while maintaining structural integrity in corrosive and abrasive environments.

Key Product Advantages

1. Extreme Temperature Resistance - Stable up to 1600°C (2912°F) continuous use

2. Superior Wear Resistance - Mohs 9 hardness outperforms most industrial materials

3. Excellent Electrical Insulation - Volume resistivity >10¹⁴ Ω·cm at room temperature

4. Chemical Inertness - Resists acids, alkalis, and corrosive gases

5. Low Thermal Expansion - Coefficient of 7-8×10⁻⁶/°C minimizes dimensional changes

6. High Mechanical Strength - Flexural strength 300-400 MPa

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
