Co-sputtered thermionic cathodes and fabrication thereof

Patent ·
OSTI ID:5637421
;
This invention relates to the fabrication of thermionic cathodes and to resultant cathode structures, and more particularly to the fabrication of themionic cathodes via sputtering technology. A thermionic cathode is fabricated by cosputtering alkaline earth oxide and metal powders under temperature and pressure conditions that ensure a metal particle size in a preferred range.
