End terminations for multilayer ceramic dielectric capacitors, particularly but not exclusively metal-impregnated capacitors, are provided by bonding a coarse ceramic powder, which is lightly coated with silver, to the capacitor ceramic by means of a glass frit in order to produce a porous pseudo end termination containing insufficient silver to provide a good contact to the capacitor electrodes. The exposed silver in the pseudo end termination is then provided with a silver sulphide layer and subsequently the pseudo end termination is impregnated with lead. The end termination thus formed is comprised substantially of lead, which is held in place by the silver sulphide layer, that is wetted by the lead, on the bonded ceramic powder, and thus low cost and readily solderable. |
