Abstract
Porous solid bodies, especially carbon bodies, are densified by chemical vapor deposition by establishing a thermal gradient within the body, thermally decomposing a gaseous precursor so deposit an electrically and thermally conductive deposit (e.g. carbon) within the body, and shifting the thermal gradient toward the lower temperature zone as deposition proceeds, by means of induction heating.
