Pyrolytic graphite is a unique form of carbon manufactured by chemical vapor deposition via pyrolysis of a hydrocarbon gas at very high temperature in a vacuum furnace. Chemical vapor deposition results in a layered structure that causes pyrolytic graphite to have thermal conductivity almost as high as copper along the plane of the plate while acting as a thermal insulator across its thickness.

Pyrolytic graphite has excellent resistance to agressive plasmas including halogen etch plasmas used in semiconductor processing. Pyrolytic graphite offers the lowest sputtering erosion rate of any material used to construct ion grids.
