Product Description

99% Refractory Alumina Ceramic Tube

Alumina ceramic is the most common technical ceramic material and relatively traditional material.

High purity aluminum oxide ceramics as a fine ceramic material is widely used in a lot of industry.

This material has superb performances in electrical insulation, high thermal conductivity, high chemical resistance, good wear resistance and low thermal expansion.

 

 Alumina Tube Applications:

1) Used for making parts for CVD, ion implants, photolithography, and semiconductor parts.

2) Used as injector tubes, gas nozzles and insulators

3) Used as material for industrial furnace due to its ablity to maintain its hardness at high temperature.

4) Used as a protector for high temperature thermal couples.

5) Used as material for the chemical industry due to its high corrosion resistance.
