Abstract

We study the processes of piezoelectric relaxation that occur in piezoelectric ceramics under the influence of weak constant electric fields. Precise measurements of the piezoresonance spectra of the ferroelectric ceramics of the PZT system at various directions of the applied constant electric field and polarization were performed using the method and program for the analysis of piezoelectric resonance for the radial and thickness resonant vibration modes of piezoceramic disks. A qualitative analysis of the time dependences of the real and imaginary parts of the piezoelectric constants of the studied piezoceramic disks obtained because of mathematical processing of sequentially measured piezoresonance spectra was carried out, and a physical interpretation of the results was proposed.
