“…Alemany et al software [16,17,18] was used here for the calculation of the complex piezoelectric, elastic and dielectric coefficients in each mode of resonance, as well as for the determination of the corresponding electromechanical coupling factors and frequency numbers. After the calculation of the complex parameters, the resonance spectrum is reconstructed as an accuracy test of the final set of calculated coefficients, quantified by the regression factor (R 2 ) of such reconstruction.…”

. Enhanced properties for ultrasonic transduction, phase transitions and thermal depoling in 0.96(Bi0.5Na0.5)TiO3-0.04BaTiO3 submicrometre-structured ceramics. Journal of Physics D: Applied Physics, IOP Publishing, 2011, 44 (33) The relaxor behaviour extends up to the isotropization point, T i =238⁰C. This can be understood as due to the coexistence of the room temperature ferroelectric phase in the stability range of the low temperature non-polar phase at zero field, between T d and T i .

“…Alemany et al software [16,17,18] is here used to analyze the impedance spectra at resonance and to calculate complex material coefficients. The thermal evolution of the dielectric permittivity and losses, as well as the one of the planar and shear modes of resonance, is also determined to evaluate the working range of the material.…”

“…At high temperature, particularly for ferroelectric and related perovskite materials, the losses due to conductivity can be very significant and the assumption of negligible loss is no longer valid. There has been a significant amount of work done to develop models for resonance in lossy piezoelectrics, usually by treating the piezoelectric, elastic and electrical coefficients as complex coefficients where the imaginary part represents the loss [29] [32], [33].…”

Currently available high performance piezoelectric materials, predominantly based on lead zirconate titanate (PZT), are typically limited to operating temperatures of around 200 °C or below. There are many applications in sectors such as automotive, aerospace, power generation and process control, oil and gas, where reliable operation at higher temperatures is required for sensors, actuators and transducers. New materials are being actively developed to meet this need. Development and application of new and existing materials requires reliable measurement of their properties under these challenging conditions. This paper reviews the current state of the art in measurement of piezoelectric properties at high temperature, including direct and converse piezoelectric measurements and resonance techniques applied to high temperature measurements. New results are also presented on measurement of piezoelectric and thermal expansion and the effects of sample distortion on piezoelectric measurements. An investigation of the applicability of resonance measurements at high temperature is presented, and comparisons are drawn between the results of the different measurement techniques. New results on piezoelectric resonance measurements on novel high temperature piezoelectric materials, and conventional PZT materials, at temperatures up to 600 °C are presented.

The temperature dependence of the ε 33 T dielectric permittivity and losses of piezoelectric Mn doped 0.65Pb(Mg 1/3 Nb 2/3 )O 3 -0.35PbTiO 3 ceramics has been measured up to 350 o C at frequencies between 1 and 100 kHz by impedance spectroscopy. The temperature dependence of the low frequency Young´s modulus and mechanical losses of the ceramics has been measured in the same temperature range by dynamic mechanical analysis in three points bending configuration. Complex ε 33 T , s 11 E compliance and d 31 piezoelectric coefficients have been obtained from radial piezoelectric resonances at temperatures up to 90 o C (before depolarisation) by an automatic iterative method. All the measurements reflect the occurrence of the ferroelectric rhombohedral to ferroelectric tetragonal phase transition, which is thougth to be responsible of the high electromechanical response of the PMN-PT system, and allow describing some of its characteristics for the investigated ceramics. Keywords: Piezoelectric ceramics, Relaxor ferroelectrics, PMN-PT, Mechanical properties, Electromechanical Properties Dependencia con la temperatura de las propiedades eléctricas, mecánicas y electromecánicas de nuevas piezocerámicas de alta sensibilidadSe ha medido por espectroscopía de impedancias la dependencia con la temperatura hasta 350 o C de la permitividad y las pérdidas dieléctricas, ε 33 T y tan δ, de cerámicas piezoeléctricas de 0.65Pb(Mg 1/3 Nb 2/3 )O 3 -0.35PbTiO 3 dopadas con Mn a frecuencias entre 1 y 100 kHz. Se ha medido por análisis mecánico dinámico en la configuración de flexión por tres puntos la dependencia con la temperatura en el mismo rango del módulo de Young y las pérdidas mecánicas de baja frecuencia de las cerámicas. Se han obtenido por un método automático iterativo los coeficientes del material ε 33 T , módulo elástico s 11 E y coeficiente piezoeléctrico d 31 en forma compleja a partir de resonancias radiales piezoeléctricas a temperaturas entre ambiente y 90 o C (antes de la despolarización). Todas las medidas reflejan la existencia de la transición de la fase ferroeléctrica con estructura romboédrica a la fase ferroeléctrica con estructura tetragonal, que se cree responsable de la alta respuesta electromecánica del sistema PMN-PT, y permiten describir algunas de sus caracterísiticas para las cerámicas concretas investigadas.
