Hydrostatic pressure and temperature induced phase transition and dielectric properties of La-doped Pb(Zr,Sn,Ti)O3 antiferroelectric ceramics were studied. The effects of temperature on the pressure-induced phase transition and the dielectric property dependence on pressure have been investigated.It was found that rise of temperature makes the ferroelectric-antiferroelectric phase transition pressure decrease.And it was observed that hydrostatic pressure makes the ferroelectric-antiferroelectric phase transition temperature decrease and the antiferroelectric-paraelectric phase transition temperature increase.The results are of help in understanding the behaviors of pressure-induced dielectric frequency dispersion and diffuse phase transition exising in the antiferroelectric ceramics with composition and polar nanodomain fluctuations.
