A heat-exchanger composed of a body of ceramic sponge defining randomly located interconnected walls bounding a plurality of randomly located interconnected cavities and a plurality of elongate heat-conductive members embedded in the body and having a surface in heat-exchanging relation with the body and an end zone at the surface of the body and another opposite end zone which is located depthwise in the body, so that, heat may be conducted between the interior of the body and the surface of the body along the heat-conductive members. The heat-conductive members may be of suitable material, such as silicon carbide or metallic glass. In another case a silicon carbide rod is attached to a ceramic plate so as to conduct heat directly from one side of the plate to the other. A method of increasing the efficiency of a tube heat exchanger with sponge baffles is described. A method of resistance heating of an auto catalytic converter is detailed.
