Momentive Performance Materials "PG" Pyrolytic Graphite
Categories: Carbon; Graphite

Material Notes: Pyrolytic Graphite (PG) is a unique form of graphite manufactured by decomposition of a hydrocarbon gas at very high temperature in a vacuum furnace. The result is an ultra-pure product which is near theoretical density and extremely anisotropic. This anisotropy results from the layered structure. As an example, PG exhibits a thermal conductivity consistent with the best conductors in the "AB" plane and lower than alumina brick in the "C" direction. Mechanical thermal, and electrical properties are generally far superior to conventional graphites. Typical properties are listed below. PG is Available as plate, free-standing shapes (crucibles, boats, tubes, etc.), and as an impermeable coating on graphite and other substrates.

APPLICATIONS:

  • Sputtering Targets
  • Ion Beam Grids
  • Ion Implant Hardware
  • Liquid Phase Epitaxy Hardware
  • Crucibles for Ultra High Vacuum
  • Thermal Insulators
  • Rocket Nozzles
  • Heater Elements
