Process for obtaining porous solid bodies of shape and porosity which are adapted as needed, made of refractory carbide with a high specific surface, characterised in that an exclusively polymeric and/or copolymerisable organic compound (for example a resin), capable of being carbonised and capable of giving a solid carbonaceous skeleton is mixed with a metal (or metalloid) powder or one of its carbon-reducible compounds, the mixture is shaped, the organic compound is crosslinked or cured, the said compound is heat-treated to carbonise between 500 and 1000 DEG C, and then to perform the carburising. …<IMAGE>… |
