Technology, Physical Properties and Phase Transitions in PMN-PT-PS Ceramics

Abstract

Technology, Physical Properties and Phase Transitions in PMN-PT-PS CeramicsSolid solution of (1-y)[(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3]-yPbSnO3(PMN-PT-PS) investigated in this paper is based on (1-x)PMN-xPT (PMN-PT) where, with increasingx, the transition from relaxor to ferroelectric properties is observed depending on composition. PMN-PT ceramics with 0.25<x<0.4 has been obtained using sol-gel method and next mixed together with PS ceramics obtained from oxides. Final sintering of ceramic samples was pressureless. We present the results of microstructure and XRD investigations, dielectric permittivity and hysteresis loops measurements vs. temperature.
