Aluminum Nitride/Boron Nitride Composite BN-AlN Ceramic Parts for Ion Source

By -

BN+ALN

BN-AlN Ceramic is made by sintering Boron Nitride (BN) and Aluminum Nitride (AIN) 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.

Source: https://www.innovacera.com/news/ceramic-heater-coil-for-vaporizer.html Not every dry herb vaporizers are the same! Especially those used ceramic heating element. The ceramic heating element is a safety and healthiest option for dry herb vaporizers, so every vaper is preferred to choose those vaporizers that carry ceramic heating element. The proponents believe that the heating element is the core of the vaporizer and primarily dictates the experience of the taste. Let's more specific, when a vaper burns tobacco, marijuana, or hemp during traditional smoking to release the active component, whatever it's nicotine, CBD, or THC, they inhale the smoke. We all know that's not good for health. Rather than burning, Vaporizer heats the liquid, wax or even dry herb to release a vapour, and a vaper inhales the vapour without any damage to their lungs or throat. And why the ceramic heating element is becoming the core part of the vaporizer? It's mainly because: 1. Ceramic ...
