摘要

Ternary ceramics 0.105PIN-0.465PSN-0.43PT (PIN-PSN-PT) with BiFeO3 addition were prepared using the two-step sintering method. Effect of BiFeO3 addition on the electrical properties and temperature stability of PIN-PSN-PT ceramics was investigated. The sintering temperatures could be reduced significantly from 1250 °C for PIN-PSN-PT ceramic to 900 °C for PIN-PSN-PT ceramics with BiFeO3 addition. For the PIN-PSN-PT ceramics with BiFeO3 ceramics, the densified microstructure could be obtained at the low temperature of 900 °C. A small amount of BiFeO3 addition could improve the phase transition temperature and piezoelectric properties. The best comprehensive electrical performances were obtained in PIN-PSN-PT-0.1wt%BiFeO3 ceramics with Curie temperature (Tc ~ 290 °C), piezoelectric constant (d33 ~ 465 pC/N), coercivity field (Ec ~ 11.41 kV/cm), plane electromechanical coupling coefficient (kp ~ 0.549) and mechanical quality factor (Qm ~ 125). Perfect temperature stability of piezoelectric and electromechanical properties was also remained below Curie temperature.
