Aluminium Nitride
- AlN is resistant to attack by most molten metals,
most notably aluminium, lithium and copper
- It is resistant to attack from most molten salts
including chlorides and cryolite
- High thermal conductivity for a ceramic material
(second only to beryllia)
And more. |
Sapphire
- Synthetically produced single crystal Sapphire.
- High thermal conductivity,
- High hardness and wear resistance
- High upper use temperature.
It is much stronger than glass and can be used as
viewing windows in high pressure and vacuum
Applications.
