摘　　要：Alternating current poling(ACP)in air by changing poling temperature(70e130℃)and voltages(2e6 kVrms/cm)on pseudo-ternary 0.24 Pb(In_(1/2)Nb_(1/2))O_(3)-0.46 Pb(Mg1/3Nb_(2/3))O3-0.30PbTiO_(3)(PIMN-0.30PT)single crystals(SCs)manufactured by continuous-feeding Bridgman(CF BM)method was investigated.Free dielectric permittivity(εT 33/ε0)and piezoelectric constant(d33)were improved to be 7000 and 2340 pC/N,which were 29%higher than those of direct current poling(DCP)at 90℃ with 4 kV/cm(εT 33/ε0=5440,d_(33)=1810 pC/N).However,phase change temperature(Tpc)decreased from 94℃ to 78℃ as opposite results reported by other groups.We demonstrated that the high temperature(HT)ACP improved piezoelectric performance of CF BM SCs,however,the Tpc were different from other crystal growth method.The well-designed ACP process was a promising method for mass production not only to enhance the electrical properties for the pseudo-ternary SCs but also reduce the risk of breakdown and realizes organic solvent-free poling process.
