This research focuses on the conductivity and dielectric properties of Bi(Ga, Fe)O3 – xPbTiO3 ceramics near the morphotropic phase boundary.
Prepared Bi(Ga, Fe)O3 – xPbTiO3 ceramics using conventional solid-state reaction methods.
Conducted impedance analysis on ceramics at various temperatures.
Evaluated dielectric properties, including constant and loss.
BGF–xPT ceramics with compositions of 0.3 and 0.35 achieved enhanced dielectric constant and as low as 0.02 dielectric loss at 100 Hz.
The T-phase-dominated ceramics exhibited high resistance at 200°C, maintaining this trait up to 420°C.
Mixed-phase ceramics showed improved electrical insulation due to high activation energy above 1 eV.

Xue et al. (2026) studied this question.
