Aluminum Nitride Series FAQ
What makes Aluminum Nitride Series superior to alumina ceramics?
The Aluminum Nitride Series offers approximately 8-10 times higher thermal conductivity than alumina while maintaining excellent electrical insulation properties. This unique combination makes it ideal for applications requiring efficient heat dissipation in electrically sensitive environments. Additionally, it has a closer thermal expansion match to silicon, reducing thermal stress in electronic packaging applications.
How does the Aluminum Nitride Series perform in high-temperature applications?
The Aluminum Nitride Series maintains its structural integrity and thermal properties at temperatures up to 1300°C in inert atmospheres. Its low thermal expansion coefficient ensures dimensional stability across wide temperature ranges, making it suitable for high-temperature processing equipment and thermal cycling applications.
What surface finishes are available for Aluminum Nitride Series components?
Aluminum Nitride Series products can be supplied with various surface finishes including as-fired surfaces, polished surfaces (up to Ra <0.05μm), and metallized surfaces (with options for thin-film or thick-film metallization). We can also provide specialized coatings for specific bonding requirements or environmental protection needs.
