摘要：

0.02Pb(Sb1/2Nb1/2)O-3-0.98Pb(1-x)Ba(x)(Zr0.53Ti0.47)O-3 (PSN-PB(x)ZT) ceramics with high Curie temperature and high piezoelectric properties were prepared by traditional solid state reaction measurement to meet the requirements for high temperature applications, and the crystal structure, dielectric, piezoelectric and ferroelectric properties were investigated. All the samples show a tetragonal crystal structure at room temperature and there was no noticeable change with the increasing of Ba2+ content. Doping of Ba2+ markedly improved piezoelectric properties of PSN-PZT, the maximum d(33)similar to 560 pC/N, T-c similar to 317 degrees C at x = 0.05. Their outstanding piezoelectric properties will drive the development of high temperature industrial applications.
