Abstract

Perovskite (1 - x)(0.06BiYbO₃-0.94Pb(Ti_0.5Zr_0.5)O₃)-xLiNbO₃ (BYPTZ-LN) ceramics were synthesized by the conventional ceramic processing. The effect of LiNbO₃ on the microstructure and piezoelectric properties was investigated. The perovskite phase and the Yb₂Ti₂O₇ pyrochlore phase are coexisting in the BYPTZ-LN ceramics sintered at 1140 °C. The material with perovskite structure is tetragonal at x ≤ 0.04 and becomes single rhombohedral at x ≥ 0.08. A morphotropic phase boundary between rhombohedral and tetragonal phases is found in the composition range 0.04 ≤ x ≤ 0.08. Analogous to Pb(Zr,Ti)O₃, the piezoelectric and electromechanical properties are enhanced for compositions near the morphotropic phase boundary. Piezoelectric constant d₃₃ values reach 290-360 pC/N. Electromechanical coefficients k_p reach 0.38-0.55. The maximum values of d₃₃, k_p and P_r are obstained as x = 0.08, accompanying with the minimum values of Q_m and E_c. The Curie temperature T_c and the maximum value of dielectric constant decrease with increasing LiNbO₃ content. BYPTZ-LN ceramics with the high d₃₃ value and the high thermal-depoling temperatures of >320 °C are obtained.
