Acid-nitrided aluminum powder (AlON)
Acid-nitrided aluminum (AlON) is a transparent optical ceramic powder with a particle size of D50~10μm. AlON is a transparent ceramic material represented by the chemical formula Al23O27N5 (or the approximate formula Al(64+x)/3O32−xNx, x ≈ 2.5) and possesses a spinel-type structure. This material is a type of acid-nitrided aluminum (AlON) that combines the excellent properties of aluminum oxide (Al2O3) and aluminum nitride (AlN).
Features
- High Hardness and Strength:
- Similar to aluminum oxide, but with superior thermal shock resistance and toughness.
- High Melting Point:
- ≥2100°C, making it suitable for use in high-temperature environments.
- Chemical Corrosion Resistance:
- Suitable for use in mechanical components and optical windows under harsh conditions.
- Crystal Structure:
- Cubic spinel phase (Fd3m).
Applications
- High-performance optical windows
- Insulating materials and thermal radiation plates
- Semiconductor and transparent ceramic components
- Transparent armor, transparent covers for electronic devices, etc.
