Abstract
Graphite products particularly suited for use in nuclear reactors are prepared by combining thermal petroleum pitch and particulated coke made from the same pitch into a moldable composition. The composition is molded into a desired shape. The shape is baked, impregnated with additional pitch, baked further, and then heated to temperatures sufficient to graphitize it. For nuclear applications a petroleum pitch low in sulfur content is preferred.
