Abstract

Graphite or carbon molded articles of high isotropy and high heat conductivity, especially useful for high temperature reactor fuel elements are prepared by pressing a mixture of a binder and a powdery carbon filler which consists partially or wholly of pyrolytically produced isotropic carbon with subsequent heat treatment of the pressed article. There is used as the filler an isotropic pyrolytic carbon made by depositing a hydrocarbon on a carbon granulate and then grinding to a particle size of less than 100 .mu.m.
