Abstract

Sintering characteristics, dielectric properties, and electro strictive 412 coefficients are reported for fourteen dopant cations incorporated in the perovskite A(B', B)03 structure of lead magnesium niobate[Pb(Plgl/3Kb2/3)03]. Two trends in the dielectric properties were found: the maximum permittivity appears to be direct lyproportional to the transition temperature, and secondly, the percent change in capacitance c?t 20 kV/cm is proportionally larger for the higher permittivity samples. Two methods to estimate the frequency dependence of the diffuseness of the phase transition showed good correlation with each other, but revealed no general trend with ionic size or valence of the modifier cations. co efficients were found to generally decrease with increasing diffuseness of the phase transitions.
