Large-strain piezoelectric ceramic material and preparation method thereof
The invention discloses a preparation method of a large-strain piezoelectric ceramic material, which comprises the following steps: synthesizing glass powder with the component of (1-x) Pb (ZraTi1-a) O3-x (Bi0. 5Na0. 5) TiO3-ywt% BaZrO3-betawt% B2O3 by using a melting-water quenching method, x and a are molar ratios, and y and beta are mass ratios; the preparation method comprises the following steps: synthesizing ceramic powder of which the component is (1-x) Pb (ZraTi1-a) O3-x (Bi0. 5Na0. 5) TiO3-ywt% BaZrO3 by using a solid-phase synthesis method; the glass powder and the ceramic powder are used for preparing the (1-x) Pb (ZraTi1-a) O3-x (Bi < 0.5 > Na < 0.5 >) TiO < 3-y > BaZrO < 3-z > GL piezoelectric ceramic material by a solid-phase sintering method, and the composition of GL is (1-x) Pb (ZraTi1-a) O3-x (Bi < 0.5 > Na < 0.5 >) TiO < 3-y > wt% BaZrO < 3-beta > wt% B2O3. The special glass component is added into the PZT-based piezoelectric ceramic for modification, so that the strain of the material is remarkably improved while the microstructure of the ceramic material is optimized.
