Aluminum Nitride/Boron Nitride Composite BN-AlN Ceramic Parts for Ion Source
BN-AlN Ceramic is made by sintering boron nitride and aluminum nitride powder. It has excellent electrical insulator, thermal conductivity, high strength, resistance to thermal shock, and strong resistance to halogen gas plasma, which is offers a wide range of applications, including components for semiconductor production equipment and components that require effective heat dissipation.
- High mechanical strength.
- High thermal conductivity.
- Low thermal expansion.
- Low dielectric loss.
- Excellent electrical insulation.
- High corrosion resistance–non-wetted by molten metals.
- Excellent Machinabilit–BN-AlN can be machined to high-precision complex shapes.
- It has excellent sealing ability to vacuum and hasn't given off much gas.
- High-frequency wave properties, allow visible infra-red light to pass through easily.
