High-performance PSN-PMN-PZ-PT quaternary texture piezoelectric ceramic material and preparation method thereof
The invention discloses a high-performance PSN-PMN-PZ-PT quaternary texture piezoelectric ceramic material and a preparation method thereof, the chemical composition molecular formula is xPb (Sc1/2Nb1/2) O3-(1-x-y-z) Pb (Mg1/3Nb2/3) O3-yPbZrO3-zPbTiO3-aEu2O3-bwt% BaTiO3, x, y, z and a all represent mole fractions, 0 lt, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0.1 < = y < = 0.25, 0.32 < = z < = 0.4, 0.005 < = a < = 0.02, and 1 < = b < = 5; the problem that the piezoelectric property and Curie temperature of existing lead-based piezoelectric ceramics are mutually restricted is solved, the [001] oriented lead-based texture piezoelectric ceramic material with the high piezoelectric property and the high Curie temperature is obtained through the design of quaternary texture ceramic components, and the method is controllable in process, low in cost and suitable for industrial production. The piezoelectric constant of the prepared ceramic material is 2.2 times that of random orientation ceramic, and the ceramic material has excellent performance.
