Entitled : Installation for the chemical vapor infiltration of a refractory material other than carbon. An armature in graphite constitutes a sealed structure housed with an inductor inside an enclosure, and defines a reaction chamber, connected outside the enclosure, with reactant gases supplying means; the enclosure is supplied with inert gas in order to keep a permanent flow of inert gas in the space surrounding the armature inside the enclosure, and the reactant products are removed from the reaction chamber and the inert gas from the enclosure by means of respective outlet pipes which join up outside the enclosure, so that substantially equal pressures are maintained in the enclosure, inside and outside the reaction chamber.
