Abstract

Lead titanate solid solutions exhibit extreme values of certain physical parameters. We have investigated ferroelectric relaxor ceramics of (1-x)[Pb(Sc1/2Nb1/2)O3] - x[PbTiO3] (PSN-PT) composition near the morphotropic phase boundary. Results are discussed taking account into the relaxor properties related to defects and disordering of the PSN-PT system..
