  • Patent number: 4213956
    Abstract: A method for the production of well-oriented carbon composites is described. The method involves applying shear or shear and compression forces to a composition containing graphite crystallites in a two-component viscous or patsy matrix, one matrix component being carbonizable to yield a high proportion of volatile products and a low proportion of carbonaceous char, the other matrix component being carbonizable to yield a low proportion of volatile products and a high proportion of carbonaceous char including meso phase carbon. The composite can be carbonized, optionally with an intermediate compression step, and may be graphitized. The products can be used in the manufacture of crucibles, containers, thermocouples and synthetic metals.
