METHOD FOR PRODUCING POROUS METAL CATHODES Russian patent published in 1995 - IPC

Abstract SU 1619727 A1

FIELD: powder metallurgy. SUBSTANCE: method involves preparing charge of a certain fractional composition from tungsten powder with an average grain size of 3.5-7 microns. Then porous cathodes are pressed, burnt and impregnated with electron-emitting substance. EFFECT: higher yield of quality cathodes and more homogeneous emitting capacity. 1 tbl
