چکیده انگلیسی
The perovskite structure of the lead zirconate-lead magnesium tungstate ceramic, 0.94PbZrO3-0.06Pb(Mg1/2W1/2)O3 (0.94PZ-0.06PMW), was prepared by the wolframite precursor method. The phase evolution with temperature in the 0.94PZ-0.06PMW ceramic was investigated, with dielectric permittivity, differential scanning calorimetry and polarization measurements. The ceramic was in the antiferroelectric phase when below 177 °C, based on dielectric measurement, and an intermediate phase was detected between 177 and 219 °C. Evidence from ferroelectric data was found to suggest that this intermediate phase is ferroelectric.
