Abstract: An indirectly heated metal cathode for an electron tube includes a metal sleeve of an Mo material, a metal emitter disposed on the metal sleeve and including Pt or Pd as a main component; and a buffer layer between the metal sleeve and the metal emitter. The buffer layer prevents Mo, an element of the metal sleeve, from diffusing into the emitter during the operation of the metal cathode so that electron-emitting performance does not decrease rapidly with operating time due to an increase in a work function. Therefore, the metal cathode satisfies a long life span requirement for large scale and high definition electron tubes.

Abstract: In a cathode with an electron-emissive material layer formed on a base containing a reducing element, a relationship of 0.24≦B/A≦0.93 is satisfied, where A denotes a surface for layer formation of the base and B represents an area where the base and the electron-emissive material layer are in contact with each other. In addition, a relationship of 0.4≦D/C≦0.7 is satisfied, where C and D denote thicknesses of the base and the electron-emissive material layer, respectively. Thus, a cathode structure is provided in which sufficient electron emission can be obtained, a decrease in electron emission with the passage of time is not much during the operation, and variations in cut-off voltage are small.

The buffer layer may be a solid solution or a multiphase alloy. A method of making the cathode by depositing a buffer between a surface of the substrate and an emissive layer, where the deposited buffer alters, randomizes, miniaturizes, and/or isolates the grain structure at a surface of the substrate to reduce the grain size, randomize crystal orientation and reduce the rate of crystal growth.

Abstract: A metal cathode for an electron-emission device, and an indirectly heated cathode assembly employing the metal cathode where the metal cathode is formed of a quaternary alloy including 0.1-20% by weight barium (Ba), 0.1-20% by weight a metallic mobilizer facilitating Ba diffusion, a metal with a difference in atomic radius of at least 0.4 Angstrom from the atomic radius of platinum (Pt) or palladium (Pd), the metal being in the range of 0.01 to 30% by weight, and a balance of at least one of Pt and Pd. The metal cathode has a low operating temperature due to its reduced work function with improved current emission capability. The metal cathode can be used for a longer lifetime at high current density. Therefore, the metal cathode can be used effectively in electron-beam devices, such as a Braun tube or picture tube, satisfying larger size, longer life span, high definition, and high luminance requirements of the devices.
