Finely divided dielectric powder compositions having the formula (Sr x Pb 1-x TiO 3 ) a (PbMg 0 .5 W 0 .5 O 3 ) b wherein n x is 0-0.10, n a is 0.35-0.5, n b is 0.5-0.65, and n a plus b equals one, n Said compositions having been calcined in air at 750°-900° 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. |
