摘要：A cathode for use in electron tubes which comprises a base metal (1) made ofnickel as a principal component and having a surface on which a porous electron emissivelayer (30) is formed. The porous electron emissive layer is of a composition comprising0.1 to 20 wt% (relative to the total weight of the porous electron emissive layer) ofscandium oxide having a layered crystalline structure dispersed in an oxide of alkalineearth metal including at least barium. This cathode can be made by preparing a solutionin which nitrocellulose is dissolved with the use of an organic solvent, mixing both ofbarium carbonate and scandium oxide having a layered crystalline structure into thesolution to provide a suspension, pulverizing solid components of the suspension for theadjustment of particle size, and depositing the suspension on a surface of the base metalto form the electron emissive layer.
