Abstract

1324124 Graphite particles GREAT LAKES CARBON CORP 19 April 1971 [6 April 1970] 25859/71 Heading C1A [Also in Division G6] Highly orientated anisotropic, spherical graphite particles are formed by heating a graphitizable carbon forming pitch to from 400 to 500‹ C. to obtain discrete spherulites of mesophase, separating the mesophase by removing the quinoline soluble portion of the heat treated product, and then carbonizing and graphitizing the spherulites, said spherulites being carbonized in a manner to prevent coalescence or being treated prior to carbonization to prevent coalescence during carbonization. Such treatment may comprise coating the spherulites with a thermosetting, e.g. an epoxy resin, or surface oxidizing them. The particles may also be carbonized on a moving bed or treated by coating them with carbon. A nuclear fuel composite may be made from a fertile nuclear fuel, an epoxy matrix and graphite particles made by the method above. The graphite material may also be used in reflector mantles.
