Product Description

Boron Nitride is often used for sintering advanced materials due to its high properties. The max working temperature of BN: 1800 ºC~1900 ºC in a vacuum; 2000 ºC~2100ºC in inert.
BN ceramic is also with high electrical insulation and good resistance to sudden cold or hot. These properties make it as a good choice for sintering quartz glass, Silicon Nitride, Aluminium Nitride, etc.
 

Here are some more characteristics of BN:
Good corrosion resistance
Good metal corrosion resistance
No wetting
Long service life
No reaction with most active metals
Good chemical stability

 

Applications:

1. Electronic parts - heat sinks, substrates, coil forms, prototypes
2. Vacuum melting crucibles
3. CVD crucibles
4. Microcircuit packaging
5. Sputtering targets
6. High precision sealing, brazing, and metallizing fixtures
7. Microwave tubes
8. Horizontal caster break rings
9. Low friction seals
10. Plasma arc insulators
11. High temperature furnace fixtures and supports

Boron Nitride can be machined to custom-designed setters. If you need protrusions on the setter, please send us a drawing.
