Abstract: This invention provides an oxide cathode comprising a body having a base layer, the body comprising a metallic component and a reducing component, and an electron-emitting layer on the base layer, wherein a diffusion inhibiting layer covers at least a proportion of at least the outer surface of the body not covered by the electron-emitting layer. The invention further provides a method of manufacturing an oxide cathode having an indirectly heated electron-emitting layer disposed on a base layer of a cathode body, which body comprises a reducing component, the method comprising forming a diffusion-inhibiting layer over at least substantially most of the surface of a cathode body, etching away the diffusion-inhibiting layer from the base layer, and forming an electron-emitting layer over the base layer.
