When excess PbO was added into the PYN-PTx system, all samples were sintered at temperatures as low as 800°C with good dielectric and piezoelectric properties. It is suggested that a liquid phase with excess PbO was formed during the sintering and improved the densification of PYN-PTx ceramics at low temperatures. For the PYN-PTx binary system, it was found that the temperature dependence of the relative permittivity follows a Curie-Weiss Law above the deviation temperature (TD) at high temperatures. Good piezoelectric properties of d 33 = 510 pC/N, ε r = 2800 at RT, k p = 0.57, and k t = 0.42 with Tc = 373°C were obtained for PYN-PT49.5 ceramics sintered at 800°C for 8h.
