  • Multilayer ceramic capacitors
    Patent number: 4228482
    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 one.
