High-temperature piezoelectric energy collection ceramic material with wide-temperature stable transduction coefficient and preparation
The invention discloses a high-temperature piezoelectric energy collection ceramic material with a wide-temperature stable transduction coefficient and preparation, and belongs to the field of piezoelectric ceramic materials. The chemical composition of a matrix of the ceramic material is zBiScO3-yBi (Zn2/3Ta1/3) O3-xPbTiO3 (x is greater than or equal to 0.605 and less than or equal to 0.64, y is greater than or equal to 0.005 and less than or equal to 0.03, and z is equal to 1-x-y). The preparation method comprises the following steps: firstly, weighing corresponding raw materials according to a stoichiometric ratio, and then sequentially carrying out wet grinding, drying, calcining, granulating, compression molding and sintering. The high-temperature piezoelectric ceramic material provided by the invention has high and thermally stable transduction coefficients in a wide temperature range, is beneficial to enhancing the working stability of a high-temperature piezoelectric energy collection device, and has remarkable social significance and application value.
