Abstract (K0.48Na0.48Li0.04)(Nb0.8Ta0.2)O3 (KNN-LT) ceramics were prepared by the traditional solid-state reaction method. The combined effects of Li and Ta additions resulted in a decrease in the orthorhombic-tetragonal (TO-T) and Curie temperature (Tc). The piezoelectric and electromechanical properties were found to be d33 ∼ 165 pC/N, kt ∼ 0.438, kp ∼ 0.363 at the sintering temperature 1178 ˚C. It has a wide temperature range for ferroelectric properties and energy storage density and possess a good temperature stability.

烧结温度对KNLNT陶瓷电性能的影响

摘要 采用传统固相反应法制备了(K0.48Na0.48Li0.04)(Nb0.8Ta0.2)O3 (KNN-LT)陶瓷。Li 和 Ta 添加的组合效应导致正交四方晶 (TO-T) 和居里温度 (Tc) 的降低。在 1178 摄氏度的烧结温度下，压电和机电性能为 d33 ∼ 165 pC/N, kt ∼ 0.438, kp ∼ 0.363。它具有较宽的铁电性能和储能密度温度范围，并具有良好的温度稳定性。
