The Influence of Hydrostatic Pressure and Electric Field to the Remanent Polarization of PbLa(Zr,Sn,Ti)O₃ Ceramic

Abstract:

Chemical composition Pb_0.97La_0.02(Zr_0.75Sn_0.136Ti_0.114)O₃ (PLZST) ceramic was fabricated by conventional solid-state reaction of oxide method. The composition is close to the AFE/FE phase boundary of PLZST ceramic phase diagram. The dependence of remanent polarization of Pb (Zr,Sn,Ti)O₃ ceramic poled under different electric fields on hydrostatic pressure was investigated with special hydrostatic pressure equipment. The results show that PLZST ceramic poled at different DC electric field is metastable state ferroelectric phase. The remanent polarization decreases sharply and is depolarization completely when hydrostatic pressure increases to a bound.
