<p>Method for the production of well-oriented carbon composites. The method involves applying shear or shear and compression forces to a composition containing graphite crystallites in a two-component viscous or pasty matrix, one matrix component being carbonisable to yield a high proportion of volatile products and a low proportion of carbonaceous char, the other matrix component being carbonisable to yield a low proportion of volatile products and a high proportion of carbonaceous char including meso phase carbon. The composite can be carbonised, optionally with an intermediate compression step, and may be graphitised. The products can be used in the manufacture of crucibles, containers, thermocouples and synthetic metals. </p> |
