Abstract
Dielectric, X-ray, and piezoelectric studies of highly-resistive Li-doped (1-x)PbFe1/2Nb1/2O3-(x)PbTiO3 (PFN-xPT) ceramics from the 0 ≤ x ≤ 0.2 range fabricated by solid-state synthesis and usual sintering have been carried out. Distinct anomalies of dielectric and piezoelectric parameters, corresponding to the transition between rhombohedral (monoclinic) and tetragonal ferroelectric phases, have been observed in pure PFN and PFN-xPT compositions with PbTiO3 content up to 8 mol.%. The x,T-phase diagram of the PFN-xPT solid solution system has been constructed using these data.
