摘要
Equipment for the preparation of electric conducting composite samples by infiltration in a mold characterized in that it essentially comprises:;a pressurization/infiltration chamber having at least one opening to connect it by means of appropriate tubes with a vacuum line and a pressure line and devices for sealing both under vacuum and under pressure;;a sample-holder, inside said chamber, made of a material with a high thermal conductivity with one or more seats in each of which a mold is housed consisting of:;a chemically inert and thermally stable tube made of a non-porous material;;a plug, situated at one end of the tube, of a material which is different from the tube;;a chemically inert and thermally stable spacer of non-porous material, situated inside the tube in contact with the plug;;a device for creating a vacuum in the chamber;;a device for pressurizing the chamber;;a device for the thermal treatment of the sample-holder.
