Abstract :
Author introduced a new pattern thermionic cathode that is used for namo materials and technologies. A tungsten framework is constructed by a low temperature process method, so that it will have an advantage on the cost and the process. This cathode looked as though it is a barium tungsten cathode, coated powder cathode (CPC). Test results showed good characteristics on current overload resistance and ability of adherence to the base metal. It has a lookout for to extend to all kinds of devices.
