GE Advanced Ceramics HTR1004 PBN/PG Heating Element


Subcategory: Graphite; Carbon; Nitride

Material Notes:
PBN/PG resistance heating elements combine the unique electrical, chemical, and thermal properties of PBN, a dielectric material, and Pyrolytic Graphite (PG), an electrical conductor, to produce a truly advanced heating system. These non-brittle refractory materials owe their exceptional purity to the high temperature, chemical vapor deposition (CVD) production method. The high thermal conductivity and anisotropy of both materials result in excellent thermal uniformity.

Performance Advantages: PBN/PG "printed circuit" heaters utilize PBN as an insulating substrate and Pyrolytic Graphite as the resistive element. This combination of unique materials delivers performance advantages not available in conventional thermal systems.

  • Operating temperatures to 1800° C.
  • Superior performance in ultra high vacuum.
  • Chemically inert to most corrosive gases, liquids.
