A new cathode is described consisting of an oxide‐impregnated nickel matrix. A sintered nickel matrix of controllable porosity is prepared and impregnated with solutions which precipitate a mixed carbonate within the matrix. The resulting cathode is a dispenser type with a minimum of surface coating. The cathodes can be activated by schedules which approximate those of a normal oxide‐coated cathode. Pulse‐emission tests of these cathodes show properties intermediate between the oxide‐coated cathode and theL‐cathode, and of the same order as the molded cathode described by McNair, Lynch, and Hannay.
