Description

99% Alumina Ceramic Insulator / Ceramic Heating Rod For Oxygen Sensor

1. Description:

Alumina ceramic (Aluminum Oxide or Al2O3) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. In addition, it is extremely resistant to wear and corrosion and is an industrial ceramic that can only be formed by diamond grinding. The melting point is very high at 2,072°C, and it is very hard. Alumina components can be widely used in electronics, pump components and automotive sensors..

2. Feature Advantages:

1) High hardness and high density

2) Low thermal conductivity

3) Chemical inertness

4) Good wear resistance

5) High Fracture toughness

6) Good insulation performance and high temperature resistance

7) A variety of specifications is available

8) Satisfy various technical requests

9) Lower medium spoilage

10) Stiffness texture

11) Good advanced ceramic materials

12) Widely apply for automotive ceramic sensor , ceramic heater ,electric heating element and pump components
