摘　　要：Ferroelectric/antiferroelectric(FE/AFE)ceramics with composition of(Pb_(0.94)La_(0.04))[(Zr_(0.70)Sn_(0.30))_(1-x)Ti_(x)]O_(3)were fabricated via solid state reaction and the effects of Ti content on dielectric and energy storage properties were studied.High releasable energy density of 1.03 J/cm^(3)was obtained when x=0:12 under 65.7 kV/cm.With increasing Ti content,both the forward and backward phase transition fields would decrease.When x=0.16,the dielectrics would be under FE state at room temperature(22℃)and the phase transition from FE to AFE and then to paraelectric(PE)was observed with temperature rise.The discharge properties were also studied and the results proved that the stored charge in AFE could be released much more completely than that in FE.
