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 wherein PA1 x is 0-0.10, PA1 a is 0.35-0.5, PA1 b is 0.5-0.65, and PA1 a 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.
