Properties of Pyrolytic Graphite
The structure, properties, and possible uses of pyrolytic graphite are presented, discussed, and compared with the properties of other high-temperature materials. Since pyolytic graphite is higlify oriented, thermal, mechanical, and electrical properties are anisotropic. Parallel to the basal planes, the material is a thermal and electrical conductor and extremely strong mechanically. Perpendicular to the basal planes, the material is a thermal and electrical insulator and mechanically weak. Graphitizing the material increases the preferred orientation and thus accentuates the anisotropy in the aforementioned properties. As a function of the testing temperature, pyrolytic graphite Becomes mechanically stronger along the basal planes. Thermally, perpendicular to the basal planes, the material continues to exhibit excellent thermal insulation.
