Boron Nitride

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 Multi-lab.

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.

Key Properties
