Способ изготовления металлопористого катода относится к электронной технике, в частности к способам изготовления металлопористых катодов для вакуумных приборов. Изобретение позволит улучшить параметры катода в приборе при сохранении исходных эмиссионных свойств катода, что достигается тем, что в зазор между губкой и корпусом запрессовывают смесь порошков тугоплавких металлов с добавкой алюминия, а спекают при 950 oC 1650 К.A method of manufacturing a metalporous cathode relates to electronic engineering, in particular, to methods for manufacturing metalporous cathodes for vacuum devices. The invention will improve the parameters of the cathode in the device while maintaining the original emission properties of the cathode, which is achieved by pressing a mixture of powders of refractory metals with the addition of aluminum into the gap between the sponge and the housing, and sintering it at 950 o C
