ABSTRACT:
Carbonaceous powders are blended with a high coking value pitch, e.g. mesophase pitch, formed into shaped bodies and then simultaneously compressed and baked in an envelope of finely divided, non-reactive particles, followed by graphitizing, if required, to produce high strength, high density carbon or graphite articles.
