  • Capacitor with noble metal electrodes
    Patent number: 4075681
    Abstract: A process for making multilayer capacitors using electrode compositions of noble metals dispersed in an inert vehicle, said compositions comprising palladium and certain amounts of additive oxide, the additive oxide being selected from among ThO.sub.2, Gd.sub.2 O.sub.3, BeO, MgO, ZrO.sub.2, Al.sub.2 O.sub.3, CeO.sub.2, Y.sub.2 O.sub.3, HfO.sub.2, BaO, and mixtures thereof. Also the resultant capacitors.

  • Process for making multilayer capacitors
    Patent number: 4063341
    Abstract: Multilayer capacitors of good electrical properties can be made by firing, in air at low temperatures, certain modified lead titanate dielectric compositions. The dielectric compositions have the formula(Sr.sub.x Pb.sub.1-x TiO.sub.3).sub.a (PbMg.sub.0.5 W.sub.0.5 O.sub.3).sub.bwhereinx is 0-0.10,a is 0.35-0.5,b is 0.5-0.65, anda plus b equals 1.
