Abstract

Carbon or graphite is impregnated with a molten metal by placing the carbon together with the metal in solid form in a total enclosure formed of an electrically conductive, non-agglomerated compacted powder, said compacted powder being surrounded by a supporting sleeve and pressure members and subjecting said enclosure to a pressure of 150-200 kg./cm.2 by means of the pressure members whilst heating to at least the m.p. of the metal, the m.p. of said powder being above the m.p. of the metal at said pressures. The compacted powder is preferably a compressed natural graphite powder. The heating of the enclosure may be by means of electrodes applied to the pressure members, or by high frequency heating. The apparatus used is described solely in relation to the Figure (not shown). The pressure may be applied by means of a screw or hydraulic jack, and the supporting sleeve may be made of graphite, or may be of metal having a lining of magnesium oxide or carbon. The material produced finds application as friction materials, electrical brushes, electrical traction shoes, collectors, electrical connectors and in nuclear energy applications. Impregnation with copper and silver is exemplified.
