METHOD FOR THE PREPARATION OF POROUS METALLIC COPPER WITH DISPERSED GRAPHITE PARTICLES

摘要

A method for the preparation of a solid product characterized in that particles of a solid material homogeneously dispersed in a porous metallic mass is prepared in a liquid containing a metal dissolved in the form of a compound soluble in the liquid, the dispersion being mixed with a reagent capable of precipitating a compound of the metal so that at least a portion of the particles is entrapped in the precipitate in a uniformly dispersed state, the precipitate containing the dispersed particles being separated from the other constituents of the mixture, and the precipitate subjected to a treatment of reduction or thermal dissociation of a temperature which is below the melting point of the metal constituting the mass, to convert the compound of the metal directly into a solid elementary metal and into a vaporized by-product without any physical or chemical alteration of the dispersed phase.
