High-Curie-temperature "receiving/transmitting" dual-purpose PZT ternary system piezoelectric ceramic material and preparation method thereof
The invention belongs to the technical field of piezoelectric ceramics, and particularly relates to a high-Curie-temperature "receiving/transmitting" dual-purpose PZT-Pb (Sn2/3Nb1/3) ternary piezoelectric ceramic material and a preparation method thereof. The ternary piezoelectric ceramic material takes lead zirconate titanate and a lead niobate stannate solid solution as main components and can be not doped or doped with at least one or more additives selected from SiO2, La2O3 and MnO2; the PZT-Pb (Sn2/3Nb1/3) ternary piezoelectric ceramic material is composed of Pb(Zr1-xTix)1-y(Sn2/3Nb1/3)yO3+awt.%SiO2+bwt.%La2O3+cwt.%MnO2; specifically, x is equal to 0.35-0.65, y is equal to 0.0-0.20, a is equal to 0-0.2, b is equal to 0-0.3, and c is equal to 0-0.1; the ceramic material has a high piezoelectric strain constant d33, a high electromechanical coupling coefficient kp, a moderate dielectric constant and a moderate mechanical quality factor, and is a "receiving/transmitting" dual-purposepiezoelectric ceramic material with excellent performance.
