Abstract

Ceramic samples of the solid solutions PbMg1/3Nb2/3O3-SrTiO3 are synthesized. The dielectric properties are studied and a phase diagram is constructed. The results obtained are discussed in terms of ideas concerning relaxor ferroelectrics for solid solutions on the PMN side and from the standpoint of potential ferroelectrics on the SrTiO3 side. The introduction of SrTiO3 into PMN gradually degrades relaxor properties, and the introduction of PMNinto SrTiO3 does not result in initiation of the ferroelectric phase transition, possibly because of the appearance of random fields in the lattice. The possibility of practical applications of the synthesized system is alsodiscussed. (C) 1999 American Institute of Physics. [S1063-7834(99)03506-6].
