2)High resistivity,
3)Low dielectric loss,
4)Good insulation,
5)Some other excellent properties

Application of aln ceramic

1. Metal & Alloy Processing
- Used in molten metal dispensing (e.g., aluminum, copper) due to non-wettability.

2. D Printing (Additive Manufacturing)
- Used in high-temperature powder deposition systems

Aln ceramics application

3.Semiconductor & LED Manufacturing

- Used in MOCVD reactors for GaN and LED production.
- Resists corrosive gases (e.g., NH3, TMGa).
