Abstract

Ceramics with the composition Pb_1-xK_2x-3yM _yNb₂O₆ (PKMN) with x = 0.29, y = 0.145 and M = Gd³⁺, Y³⁺ were synthesized by the solid-state reaction route between the corresponding oxides and carbonates. The crystal structure was confirmed by X-ray diffraction (XRD). The temperature dependence of dielectric properties were measured from 35 to 595°C. Well-developed P-E (polarization-electric field) hysteresis loops were observed in the materials. Determining the piezoelectric constants, K_p = 20%, K_t = 49%, d₃₃ = 110, and quality factor, Q_m = 33, reveals that the material Y³⁺-modified PKN can be useful for transducer applications.
