Abstract

METODO PARA LA FABRICACION DE UN CATODO EMISOR, QUE COMPRENDE COMPUESTOS DE BARIO Y ESCANDIO QUE SUMINISTRAN BARIO A LA SUPERFICIE EMISORA DE UN CUERPO DE CATODO. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UN CATODO A PARTIR DE UN METAL O ALEACION DE ALTO PUNTO DE FUSION, PARA LO CUAL SE PRENSA EN UNA MATRIZ ADECUADA UNA CANTIDAD DE METAL DE ALTO PUNTO DE FUSION EN POLVO, AL QUE SE LE HA MEZCLADO AL MENOS PARCIALMENTE UN OXIDO DE ESCANDIO; Y POR ULTIMO, SE SINTERIZA EL CUERPO PARA FORMAR EL CATODO Y A CONTINUACION SE PROPORCIONA AL CATODO FORMADO EL MATERIAL EMISOR.
