| titleOfInvention | cathod of color cathode ray tube |
| abstract | The present invention relates to a cathode structure which improves the electron emission characteristics of a cathode for a color cathode ray tube and enables stable electron radiation for a long time even under high current density.n n n Accordingly, the constitution includes a trace amount of reducing elements such as silicon (Si) or magnesium (Mg) on the top of a cylindrical cathode sleeve in which a cathode heating heater is inserted, and at least barium on a gas metal 11 composed of nickel (Ni) as a main component. In an oxide cathode having an electron emitting material layer composed of a metal compound containing (Ba),n n n The electron emitting material layer is composed of a single layer composed of an alkaline earth metal compound, a rare earth metal compound, and an actinium group metal compound, or a first electron emitting material layer composed of an alkaline earth metal compound and a rare earth metal compound is formed, and The second electron emitting material layer composed of an alkaline earth metal compound and an actinium group metal compound is formed on the upper surface of the first electron emitting material layer. |
