Dielectric and piezoelectric properties of PbFe1/2Nb1/2O3-PbTiO3 ceramics from the morphotropic phase boundary compositional range

Dielectric, X-ray, and piezoelectric studies of highly-resistive Li-doped (1-x)PbFe 1/2 Nb 1/2 O 3 -(x)PbTiO 3 (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, c...

Zusammenfassung:Dielectric, X-ray, and piezoelectric studies of highly-resistive Li-doped (1-x)PbFe 1/2 Nb 1/2 O 3 -(x)PbTiO 3 (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 PbTiO 3 content up to 8 mol.%. The x,T-phase diagram of the PFN-xPT solid solution system has been constructed using these data.
