Abstract

Low temperature sintering of Pb(Sc_1/2Nb_1/2)O₃-PbTiO₃ (PSNT) piezoelectric materials was studied with the use of LiBiO₂ (LBiO) as a sintering aids. The sintering aids improved the sinterability of manganese modified PSNT ceramics due to the effect of LBiO liquid phase, resulting in a reduction of the firing temperature by ∼350-400 °C. The microstructure of the sintered materials, together with the dielectric and piezoelectric properties were investigated. The 1 wt.% LBiO-added PSNT-Mn ceramics sintered at 950 °C for 2 h exhibit piezoelectric coefficient of 340 pC/N with a Curie temperature around 263 °C, the electromechanical coupling factor k_p, dielectric constant K₃₃^T and mechanical quality factor Q were found to be 61.5%, 1300 and 800, respectively, demonstrating that it is a promising material for multilayer piezoelectric actuator and transformer applications.
