Dielectric Properties and Phase Transition Temperature of PMN-BT Ceramics
Source abstract
Abstract
The dielectric properties of PMN-BT solid solution ceramics were systematically studied. The change of the transition temperature with composition is in the form of U curve and the possible cause may be existing of paraelectric phase Ba(Mg1/3Nb2/3)O3 in PMN-BT ceramics. The effects of composition on dielectric relaxation for PMN-BT ceramics were studied. With increasing BT content, dielectric relaxation of PMN-BT ceramics was increasing first, then decreasing. The characteristics of phase transition temperature of the ferroelectric solution composed of two perovskite compound were also discussed.
