Hot Pressed BN Boron Nitride Ring

Solid Boron Nitride, is a excellent machinable advanced ceramic Is a unique material, Boron Nitride Solid solves problems that could not possibly be tackled with other compositions such as Al2O3 or SiC.

Boron Nitride in Solid form handles temperatures over 2000°C and, depending on the grade, carries a dielectric strength of nearly 1000 volts/mil. Hot pressed in billet form Boron Nitride can easily be machined into rods, bars, plates and even custom shapes this can all be carried out in house at UNIPRETEC.

Because of its highly exceptional characteristics Boron Nitride makes it ideal for fixture or jig materials for sealing or brazing operations in induction, vacuum and atmosphere furnaces; for molten metal crucibles; heat sinks and high temperature insulators.

Hot pressed boron nitride, sometimes is referred to as 'white graphite' has a platey, hexagonal structure. This type of bond is equal to that found in diamonds, yields excellent physical, thermal and electrical performance under a wide range of uses.  

Hexagonal Boron Nitride can be easily machined into complex shapes using conventional high speed cutting tools.
