The invention relates to a polygranular carbon member of granular or, respectively, pulerulant and/or fibrous carbon particles as filler materials and of a binder, which has been subjected to a thermal treatment for consolidation of the binder, as well as to a method of producing such a carbon member. That kind of a carbon member is to be dimensionally stable, self-supporting and rigid also in the case of extremely low wall thicknesses and relatively large surface area dimensions, and it is to be able to be produced economically. For this purpose, it is suggested according to the invention that carbon materials, such as coke, carbon black, carbon filters, natural or synthetic graphite and the mixtures thereof, are incorporated as filler material, and that the carbon member has at first, prior to the thermal treatment and under the influence of shearing forces, been shaped from a plastic carbon composition (mass) with a carbonaceous, cokable binder content of from 50 to 150% by weight, based on the filler material, into a thin, plate-shaped member and through the subsequent thermal treatment into a sheet-like article of a specific configuration.

A polygranular carbon member of granular or, respectively, pulverulent and/or fibrous carbon particles as filler materials and of a binder, which has been subjected to a thermal treatment at a temperature between about 700 and 1000°C. for carbonizing and consolidating the binder, that as filler material carbon materials such as coke, carbon black, carbon fibers, natural or synthetic graphic and the mixtures thereof are incorporated and that said carbon member has been configured prior to said thermal treatment and under the influence of shearing forces from a plastic carbon composition having a content of from 50 to 150% by weight of cokable binder, based on said filler material, at first into a thin, plate-shaped member and thereafter through said thermal treatment into a rigid, dimensionally stable, flexible, sheet-like structure of a specific configuration. A carbon member as defined in claim 1 wherein the thickness of the single-layer sheet-like material is between 0.1 and 5.0 mm.
