Electrically induced antiferroelectric-ferroelectric phase transformations in lead-zirconate titanate stannate ceramics

Antiferroelectric(AFE)-ferroelectric(FE) phase transformations in the tin modified lead zirconate-lead titanate (Pb(Zr,Sn,Ti)O$\sb3,$ i.e., PZST) system were investigated. The field-induced transformation behavior was studied as a function of temperature, pressure, and microstructure. Emphasis is placed on (i) the thermal stability of the AFE-FE transformation, including thermal hysteresis, (ii) microstructure-property relations, and (iii) electromechanical response of the field-induced transformation behavior for actuator applications. A thermodynamic model is proposed to account for the thermal stability of the field-induced transformation characteristics, including reversible and irreversible phenomena. Results are interpreted in terms of thermodynamic relations, and are shown to be interrelated and self-consistent. Fundamental issues underlying the thermodynamic relationships are discussed from the perspective of lattice dynamics theory.
