Abstract

The sintering behavior of 0.36BiScO₃-0.64PbTiO₃ (0.36BS-0.64 PT) ceramics was studied to investigate the effect of grain growth by the sillenite Bi₁₂PbO₁₉ (BP) phase on their piezoelectric properties for application in high-temperature piezoelectric devices. The BP phase formed during calcination at temperatures <750 °C led to a grain growth anomaly of the 0.36BS-0.64 PT ceramics sintered at 1000 °C. This phase assisted the grain growth of the 0.36BS-0.64 PT ceramics by liquid phase sintering. In particular, the 0.36BS-0.64 PT ceramic calcined at 700 °C exhibited excellent piezoelectric properties with a d₃₃ of 531 pC/N, g₃₃ of 41×10⁻³ Vm/N, k_p of 61.8%, and Q_m of 16. In addition, the 0.36BS-0.64 PT ceramics exhibited ferroelectric relaxor-like characteristics with an extremely large relaxation coefficient (γ) of 1.94 along with high maximum dielectric permittivity temperature (426 °C).
