Pyrolytic Graphite

Pyrolytic Graphite (PG) is a unique form of graphite manufac- tured by decomposition of hydrocarbon gas at very high tem- perature in a vacuum furnace. The result is an ultra-pure product which is near theoretical density and extremely anisotro- pic. As an example, PG exhibits 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.

PG is available as plate and as an impermeable coating on graphite and other substrates.
