摘要/Abstract

摘要： 以氢氧化钾(KOH)和五氧化二铌(Nb₂O₅)为原料, 通过微波水热法在200℃下合成出具有不同晶相、形貌的铌酸钾粉体(KNbO₃). 当KOH浓度在10~14mol/L时, 可以制备出纯相的KNbO₃粉体. X射线衍射(XRD)、场发射扫描电镜(FESEM)和透射电镜(TEM)分析可知, KOH浓度由10mol/L增大到15mol/L时, KNbO₃粉体由斜方六面体变为正交相, 再转变为四方相, 对应的形貌也由金字塔状变为棒状, 再转变为立方状. 当KOH浓度增大到15mol/L时, 出现了Nb₂O₅杂相. 常压烧结制备了KNbO₃陶瓷, 其介电常数达到302, 介电损耗为0.023, 压电常数达到80 pC/N, 平面机电耦合系数为0.17, 机械品质因数为70, 居里温度为420℃, 正交?四方相变温度为223℃.

Abstract: KNbO₃powders with different phases and morphologies were successfully synthesized through the reaction between KOH and Nb₂O₅by microwave-assisted hydrothermal method at 200℃. Pure KNbO₃ crystals were obtained when the concentration of KOH was maintained from 10mol/L to 14mol/L. According to the XRD, FESEM and TEM characterizations, it could be observed that as increasing the concentration of KOH from 10mol/L to 15mol/L, the KNbO₃ phases changed from rhombohedral to orthorhombic then to tetragonal, and the corresponding morphology of the KNbO₃ powders changed from pyramid-like to rod-like then to cubic-like. Some Nb₂O₅phases were found when the concentration of KOH increased to 15mol/L. KNbO₃ceramics were sintered from the KNbO₃powders by conventional processing. The piezoeletric properties such as the piezoeletric constant d₃₃, the relative permittivity ε₃₃/ε₀, the dielectric loss tanδ, the electromechanical coupling factors kp and the mechanical quality factor Q_m of the sintered KNbO₃ ceramics were 80 pC/N, 302, 0.023, 0.17, 70, respectively. The tetragonal to orthorhombic and cubic to tetragonal phase transitions temperatures were 223℃ and 420℃, respectively.
