Temperature Stability of Nb-doped PMS-PZ-PT Ceramics

Abstract

Abstract: The influences of Nb-doping on the temperature stability of PMS-PZ-PT ternary system ceramics were investigated. The stable temperature dependence of resonance frequency, electromechanical coupling coefficient K₃₁and piezoelectric constant d₃₁ were measured. Results show that the donor dopants can not only optimize piezoelectric properties of the system, but also improve the temperature stability. So the modified PMS-PZ-PT ceramics can achieve the requirements for high-power piezoelectric devices such as ultrasonic motors.

Key words: PMS-PZ-PT, temperature stability, Nb-doping, high power
