Abstract
Method of manufacturing an indirectly heated cathode for use in an electric discharge tube, the space between the filament wire and the support of the emitting layer being filled with a porous, insulating ceramic mass, CHARACTERIZED by the surface of the wire The filament and/or the inner surface of the cathode support are covered with a layer of a ceramic suspension containing constituents that develop gas, the filament wire being subsequently inserted into the cathodic support and filling the ceramic substance, due to its formative effect. foam, the internal space of the cathodic support, after which the foam is sintered and degassed.
