About Shapal Ceramics
Shapal, a translucent Aluminum Nitride, is a machinable ceramic with high strength and thermal conductivity. It is a very good electrical insulator. Shapal has zero porosity, is able to seal well under vacuum, and has a low thermal expansion that is coupled with a high heat resistance.
Shapal Applications
- Vacuum parts
- Refractory components
- Heat sinks
- Igniter insulators
- Electrode clamps
