Manganese niobate doped lead ytterbium niobate-lead zirconate titanate piezoelectric ceramic and preparation method thereof
The invention discloses a manganese niobate doped lead ytterbium niobate-lead zirconate titanate piezoelectric ceramic and a preparation method thereof. The chemical formula of the manganese niobate doped lead ytterbium niobate-lead zirconate titanate piezoelectric ceramic is xwt.% MnNbO4-yPb (Yb0. 5Nb0. 5) O3-zPbZrO3-(1-y-z) PbTiO3, and x is larger than or equal to 1.4 and smaller than or equal to 1.8, y is larger than or equal to 0.1 and smaller than or equal to 0.14, and z is larger than or equal to 0.37 and smaller than or equal to 0.42. According to the invention, the manganese niobate doped lead ytterbium niobate-lead zirconate titanate (MnN-PYN-PZT) piezoelectric ceramic with relatively high mechanical quality factor and excellent piezoelectric coefficient is obtained by doping manganese niobate and adopting a solid-phase sintering method; the piezoelectric ceramic can better meet the basic performance requirements of high-power devices such as a high-power ultrasonic welding machine and an ultrasonic flaw detector.
