Hot Pressed Boron Nitride Shapes

Hot pressed BN is compacted at temperatures up to 2000°C and pressures up to 2000 psi to form a dense, strong engineering material that is easily machined.  It is available in standard and custom hot pressed shapes and has several unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.

Material Grades

HBC & HBT

  • High purity hot pressed boron nitrides
  • Diffusion bonded (no binder)
  • Low dielectric constant & loss tangent
  • Minimal moisture pick-up
  • Chemically purified (HBC)
  • Thermally purified (HBT)

HBN

  • Boric oxide binder
  • Highest density
  • Highest strength

HBR

  • Calcium borate binder
  • High density
  • Best moisture resistance

 


Thermal Management

The unique combination of excellent electrical insulation and thermal conductivity makes BN very useful as a heat sink in high power electronic applications.  Its properties compare favorably with beryllium oxide, aluminum oxide and other electronic packaging materials, yet  is easier to form and finish.

 

 

High Temperature Environments

Temperature stability and excellent resistance to thermal shock makes BN the material of choice in the toughest high temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing.  

  

  

Molten Metal Handling

BN is inorganic, inert, nonreactive with halide salts and reagents, and is not wet by most molten metals and slags.  These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
