Abstract
Graphite composite articles comprising a graphite structure formed from a porous graphite material and an impregnant selected from the group consisting of glass precursors and ceramic precursors, filling the pores and coating the surface of the structure. The present invention also provides a process for the manufacture of graphite composites comprising the steps of infiltrating a porous graphite structure with a material selected from the group consisting of glass precursors and ceramic precursors and subsequently converting the precursor to a glass or a ceramic respectively.
