Piezoelectric energy collection ceramic material with high depolarization temperature and large piezoelectric property and preparation
The invention discloses a piezoelectric energy collection ceramic material with high depolarization temperature and large piezoelectric property and preparation, and belongs to the field of piezoelectric ceramic materials. The chemical composition of a matrix of the ceramic material is zBiScO3-xPbTiO3-yBi (Zn1/2Ti1/2) O3 (x is more than or equal to 0.605 and less than or equal to 0.64, y is more 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 depolarization temperature and high piezoelectric property, is beneficial to further improving the working temperature and the electromechanical transformation capability of a high-temperature piezoelectric energy collection device, and has remarkable social significance and application value.
