PYN-PZT-based high-temperature texture piezoelectric ceramic, preparation method and application
The invention discloses a PYN-PZT-based high-temperature textured piezoelectric ceramic, a preparation method and application, the molecular formula is (1-x-y) Pb (Yb1/2Nb1/2) O3-yPbZrO3-xPbTiO3, x is 0.2-0.7, y is 0.2-0.7, and 1-x-y is greater than 0; the method comprises the following steps: firstly preparing precursor powder, then burdening, carrying out ball milling, drying, grinding, sieving, pre-sintering, carrying out secondary grinding, carrying out secondary ball milling, carrying out tertiary grinding and carrying out secondary sieving to obtain PYN-PZT matrix powder, preparing textured ceramic by combining the PYN-PZT matrix powder, and sequentially polishing, silvering and polarizing the textured ceramic to obtain the PZT-based high-temperature textured piezoelectric ceramic. The method is used for manufacturing an ultrasonic transducer or a hydrophone. The problems that in the prior art, the Curie temperature is low, and high texture degree, high piezoelectric performance and electromechanical performance are difficult to achieve in textured piezoelectric ceramic with high PZT content are solved.
