Abstract

Microstructure and dielectric properties of relaxor ferroelectrics in the solid solution, formulated 0.67Pb(Mg_1/3Nb_2/3) O ₃-0.33PbTiO₃ + 2 mol% RE (RE = Sm, Nd, Yb or Ce), have been investigated. The effects of these dopants on microstructure, maximum dielectric constant (K_max) and degree of ordering, etc. have been studied. It was found that doping of Sm, Nd and Ce reduced K_max from 23924 to 14921, 13466 and 12511 respectively, while the doping of Yb increased K_max to 27759. The variation of K_max is analyzed according to grain size, domain structure and order-disorder behavior. Diffuseness of the phase transition is calculated to indicate order-disorder behavior, which is roughly opposite to that of K_max. The present results show that order-disorder behavior is the key factor on K_max of PMN-PT ceramics near morphotropic phase boundary.
