Crystal structure, microstructure and electrophysical properties of highly sensitive ferroactive materials based on the Pb(Zr1-xTix)O3 system

[Display omitted] •Selected promising compositions - the basis of functional materials.•Comprehensive studies of PZT-based materials have been carried out;•Based on the results achieved, highly sensitive materials were obtained;•Materials obtained are promising for accelerometers, ultrasonic flaw detectors etc. High-strength ferroelectric materials based on a multicomponent system with the presence of the PZT, characterized by a high Curie temperature, TC, the increased sensitivity to mechanical stress, and long-term stability, were manufactured with help of by the two-stage solid-phase synthesis followed by sintering using the conventional ceramic technology. Based on the studies of the dielectric properties in the temperature range of (300–800)K, the frequencies of the alternating electric field (25–2 × 106)Hz of AC field were found, and the features of the observed dispersion phenomena were revealed. It was shown that these materials also have stable piezoelectric properties over a wide temperature range. A conclusion about the expediency of using the obtained data in the development of accelerometers, ultrasonic flaw detectors, nondestructive testing devices, etc. with similar materials has been made.
