ABSTRACT:
Graphite molding powders are prepared which contain phenol-formaledehyde as a binder and which are intended for use in the manufacture of graphite molded articles, especially fuel inserts, fuel elements and absorber elements for high temperature reactors by mixing a graphite powder with a phenol formaldehyde binder and subsequent heat treatment, in a given case in admixture of coated fuel, fertile or absorber particles. The invention resides in not adding to phenol-formaldehyde as such to the graphite powder but as the starting components namely phenol and formaldehyde or source of formaldehyde and heating the mixture to the resin condensation temperature.
