Dense PZT 95/5 ferroelectric ceramics were fabricated by solid-state reaction method.Low-temperature phase structures and electrical properties of dense PZT 95/5 ferroelectric ceramics were investigated.X-ray diffraction(XRD) results show that the phases of both poled and unpoled dense PZT 95/5 ferroelectric ceramics almost keep unchanged at different temperature.The remanent polarization calculated from the pyroelectric current and the resistance of dense PZT 95/5 ferroelectric ceramics changes little at l...
