Product Description

90% Aluminum Oxide Ceramic Insulation Rod / Ceramic Insulator For Oxygen Sensor​

 

1. Description:

Alumina ceramics are one of the most robust ceramics available. Alumina ceramics have outstanding properties that make them one of the most widely used ceramics for structural, wear, and corrosive environments. Additionally, with their exceptional electrical properties, high purity alumina ceramics are one of the preferred materials for semiconductor chamber applications.

 

2. Feature Advantages:

1) High elasticity modulus 

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision

7) High stability

8) High welding sealing performance
