  • 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.
    Type: Grant
    Filed: May 21, 1976
    Date of Patent: December 20, 1977
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Robert Joseph Bouchard, Lothar Heinrich Brixner, Michael John Popowich
  • Dielectric powder compositions
    Patent number: 4048546
    Abstract: Finely divided dielectric powder compositions having 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.b whereinx is 0-0.10,a is 0.35-0.5,b is 0.5-0.65, anda plus b equals one,Said compositions having been calcined in air at 750.degree.-900.degree. C. for at least 5 minutes. These powder compositions may be formed into the desired shape and sintered in air at reduced temperatures to produce dielectric bodies of improved properties.
