Specifications

Boron Nitride PBN parts
1:Non-toxic
2:Good thermal conductivity
3:Chemically inert to almost all metals, liquids and gas

PBN products have been widely applied in such areas as avionics, semiconductor, electronics , chemical , metallurgical, and pharmaceutical industries. Applications include:

• PBN crucibles and boats for single crystal growth of compound semiconductors, e.g. GaAs, InP, etc.
• PBN crucibles and hardware for high temperature vacuum processes, e.g. MBE, aluminum evaporation, etc.
• PBN infrared polarzers
• PBN support rods in TWT helix structure
• Electrical insulators in high temperature vacuum equipment
• Heating elements for silicon wafer processing equipment
• PBN-coated graphite susceptors, heat shields, nozzles and evaporation boats for military and industrial applications.
