摘要：

The microstructure, electrical property and strain performances of the Pb0.97La0.02(Zr0.775-xSn0.145+xTi0.08)O-3 (PLZT) antiferroelectric ceramics which were prepared by conventional solid state synthesis (CSS), hot-pressing sintering (HP), aqueous gelcasting assisted solid state sintering method (GASS) and aqueous gelcasting assisted hot-pressing sintering (GAHP) method were compared and investigated systematically. Compared with the ceramic obtained by CSS, Pb0.97La0.02(Z(r0.66)Sn(0.26)Ti(0.08))O-3 ceramic prepared by timesaving HP showed higher density and more homogeneous microstructure, whose saturated polarization (P-s) and maximum longitude strain (S-max) were 42C/cm(2) and 0.45% respectively. Finally, aqueous gel-casting assisted method was used to develop the microstructure, electrical property and strain properties of materials. Pb0.97La0.02(Z(r0.70)Sn(0.22)Ti(0.08))O-3 ceramic obtained by more cost-effective GASS (P-s = 40C /cm(2), S-max = 0.47%) exhibited 37.5% larger in saturated polarization and 36.2% higher in maximum longitude strain than by CSS.
