Chapter 17 - Isotropic High-density Graphite and Nuclear Applications

Abstract

Production, properties and applications of isotropic high-density graphite are reviewed by focusing on those produced by the random aggregation of micrometer-sized particles of needle-like coke via cold isostatic pressing (CIP), followed by carbonization and graphitization. In order to attain high density, the cycle of pitch impregnation, carbonization and graphitization is often repeated. After brief description on the production, the properties are summarized and discussed on the application to nuclear reactors, fission and fusion reactors. For nuclear fission reactors, high temperature gas-cooled reactors, they are used as structural components, and for nuclear fusion reactors as the first wall of divertors.
