Relaxor behavior of piezoelectric Pb(Yb1/2Nb1/2) O3-PbTiO3 ceramics sintered at low temperature

Journal Article


Abstract


  • A (100-x)Pb(Yb1/2Nb1/2)O3-xPbTiO 3 [PYNPTx] solid solution system with 49.0≤×≤51.0 was prepared using a conventional ceramics process and sintered at low temperature. When excess PbO was added into the PYNPTx 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 d33= 510 pC/N, εr=2800 at RT, kp=0.57, and kt=0.42 with Tc= 373°C were obtained for PYN-PT49.5 ceramics sintered at 800°C for 8 h. © 2011 Springer Science+Business Media, LLC.
