METHOD FOR MANUFACTURING OXIDE CATHODE Russian patent published in 1997 - IPC

Abstract RU 2089002 C1

FIELD: manufacture of electronic devices, high-efficiency thermal emitters. SUBSTANCE: method allows to enhance morphological homogeneity of active mass of oxide cathode, to raise anode current, steepness of decay of volt-ampere characteristic and pulse emission of tube by irradiation of emitting composition of active mass with gamma quanta with dosage 10⁴...10⁶ rad which is carried out with simultaneous annealing at temperature 800-900 C in atmosphere of carbon dioxide for 30-60 min. EFFECT: increased efficiency. 1 dwg, 3 tbl
