Abstract

In a graphite material comprising a mass of expanded graphite particles compressed together so as to form a graphite foil, the graphite foil is provided with a plurality of apertures disposed on at least one surface thereof so as to substantially prevent formation of bubble-like deformations which occur when the graphite foil is heated and/or placed in a vacuum. The method of making the invented foil and devices used to make said foil are also disclosed.
