Abstract
Abstract Dense graphite products having an open porosity of less than one per cent are prepared by employing an improved graphitizable mixture consisting essentially of a carbonaceous filler, a carbonizable resin binder, and a small quantity of dissolved camphor. This mixture can be readily formed into products of the desired configuration by extrusion, molding, slip casting, or spraying.
