摘要
采用传统固相反应法制备了Mn掺杂的(K,Na,Li)(Nb,Ta)O3无铅压电陶瓷,研究其介电和压电性能。实验结果表明,MnCO3的加入使样品的烧结温度降低,提高了陶瓷的致密性和压电性能。当MnCO3的添加质量分数为0.2%的时候,样品的性能达到最佳。
Lead-free piezoelectric ceramics MnCO3 - doped （K,Na,Li）（Nb,Ta）O3 were prepared using traditional solid - state reaction method, and the piezoelectric properties were investigated. The dielectric and piezoelectric constants with different doping value were studied. The results indicated that the doping of Mn could decrease sintering temperature, and improve density the ceramic as well as piezoelectric properties. The ceramics doped with 0.2 wt% MnCO3 had the best piezoelectric properties.
