Device and procedure for its use for the infiltration of porous preforms with liquid metals of high vapor pressure, this being greater than 10-3 mm hg, which is mounted inside an infiltration chamber conventional and comprises a porous preform, an infiltration crucible that houses in turn said porous preform and the metal that will be infiltrated therein by gas pressurization, a saturation crucible arranged in such a way that it is inverted with respect to the infiltration crucible covering it and thus forming a closed saturation chamber, simple to assemble, adaptable to any conventional infiltration device and which avoids appreciable losses of metal, thus enabling the process of infiltration of the metal into the porous space of the preform.
