    摘要: An electron-emitting material contains a first metal component selected from Ba, Sr and Ca and a second metal component selected from Ta, Zr, Nb, Ti and Hf and also contains oxynitride perovskite. The electron-emitting material has improved electron emission characteristics, restrained evaporation at elevated temperatures, and minimized consumption by ion sputtering. The electron-emitting material is prepared by firing a metal component-containing raw material disposed in proximity to carbon in a nitrogen gas-containing atmosphere to thereby create oxynitride perovskite.

    摘要: The invention provides a voltage-dependent nonlinear resistor porcelain in the form of a ZnO system sintered body comprising zinc oxide as a major component and at least one of rare earth element oxides, cobalt oxide, chromium oxide, at least one of Group IIIb element oxides, at least one of Group Ia element oxides, 0.01 to 2 atom % calculated as Ca of calcium oxide, and 0.001 to 0.5 atom % calculated as Si of silicon oxide as subordinate components, the atomic ratio of calcium to silicon (Ca/Si) ranging from 0.2 to 20. With the atomic ratio of calcium to silicon (Ca/Si) set between 0.2 and 20, preferably between 2 and 6, the element has a significantly increased load life at high temperature and humidity. The element experiences less deterioration of the asymmetry of its volt-ampere characteristic between different directions of DC conduction. If magnesium oxide is added to the composition in an amount of 0.05 to 10 atom % calculated as Mg, the benefits are enhanced, with grain growth suppressed and leakage current minimized even on high temperature firing.

    摘要: Semiconducting ceramics are produced by firing a semiconducting composition of the barium titanate type containing vanadium oxide in the amount of 0.001 to 0.5 wt%. A change in the specific resistance over the range of the temperature at which the positive temperature coefficient characteristic of resistivity (PTCR) is exhibited can be increased by as much as 10.sup.5 times and the specific resistance value at room temperature can be controlled at a desired value. By further adding silicon dioxide to the above composition in the amount of 0.05 to 1.5 wt% the above effects can be enhanced, especially the specific resistance at ambient temperature.
