Product Description

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.

The ion source is a device that creates atomic and molecular ions, which is in the vacuum chamber. Aluminum Nitride/Boron Nitride Composite has excellent electrical insulator, thermal conductivity, sealing ability to vacuum and hasn't given off much gas. So it is plays an heat sinks and thermal transfer plate role in ion sources.

Material Advantages:
>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.
 

Applications:
>Heat sinks
>Vacuum components
>Components where low dielectric constant and dissipation factor are required
>Parts and components where a low coefficient of thermal expansion is required
>Electronic components where electrical insulation and heat dissipation are required
>Electric propulsion discharge channels for Hall Effect Thrusters
