High-strain-performance sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic material obtained through bismuth reduction and preparation method of high-strain-performance sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic material
The invention discloses a high-strain-performance sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic material obtained by bismuth reduction and a preparation method thereof, and aims to solve the problems that defect-modified sodium bismuth titanate ceramic is unstable in performance and needs to be driven by a large electric field and the like. The chemical general formula of the sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic material is (Na < 0.5 > Bi < 0.5 >) < 0.75 > (1-x) Sr < 0.25 > (1-x) Pb < x > TiO < 3 >, and the sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic material is prepared by mixing Na2CO3, SrCO3, TiO2, Bi2O3 and PbO according to the stoichiometric ratio of (Na < 0.5 > Bi < 0.5 >) < 0.75 > (1-x) Sr < 0.25 > (1-x) Pb < x > TiO < 3 > and then pressing and sintering. The maximum strain of the sodium bismuth titanate-strontium titanate-lead titanate ternary ceramic under an electric field of 80kV/cm is 2.77%, and the strain memory effect is 1.75%.
