Production Description:

Ceramic protection tubes of Alumina materials, which are closed one end, are manufactured in a

single-step process and act as protective sheath against penetration from the outside atmosphere

into the measurement system.

 

Alumina ceramic Main Features:

1. Good thermal shock resistance

2. Good resistance for chemical attack
3. High corrosion and wear resistance
4. High temperature resistance
5. High mechanical strength
6. High compressive strength
7. High hardness

 

Application:

1. Superior gas and vacuum tightness

2. Electrical insulating

3. Non-reactive and recommended for use with platinum, tungsten and molybdenum thermocouple alloys
