A method is described for producing layered structures comprising a porous metal layer and a ceramic containing layer comprising wherein a porous green ceramic layer is provided, and thereafter loose metal particles are applied to the green ceramic layer before sintering. In one embodiment, the green ceramic layer, after application of the loose metal particles, is dried to drive off the solvent and cause interpenetration of the metal particles. In another embodiment loose particles can be removed from the composite such as by shaking, and the green ceramic/loose metal particles composite compressed to cause further interpenetration of the metal particles prior to sintering.
