Abstract

Method of manufacturing an indirectly heated cathode comprising a heating conductor that is in thermal contact with the support of the emitting layer through insulating ceramic material, characterized in that the heating conductor is embedded in a mixture of silicon oxide and/or a metal oxide which is fusible between 1150º C and 1700º C and which is put in contact with the support of the emitting layer, the mixture then being fused to both the heating conductor and the support of the emitting layer.
