Abstract
0.4Pb(Mg1/3Nb2/3)O3-0.3Pb(Mg1/2W1/2)O3-0.3PbTiO3 + xMgO (x = 0 to 0.04 ) were prepared by a metal alkoxide method. The percent of perovskite phase of the calcined powders increased with increased calcination tem peratures. About 89% of perovskite phase was obtained at 1050-degrees- C. The dielectric constant of the pellets fired at 1100-degrees-C was increased by the addition of 10 wt% excess Mg(OC2H5)2 and had a maximu m value of 7532 at 1 kHz.
