Texturing piezoelectric ceramic material and preparation method thereof
The invention discloses a texturing piezoelectric ceramic material and a preparation method thereof. The piezoelectric ceramic material consists of template material crystals and a base body material; the Bi4Ti3O12, Na0.5Bi4.5Ti4O15 or Na0.5Bi0.5TiO3 template material crystals with orientation 001 form direction arrangement in the base body material; the base body material has the following chemical expression: (1-x)Bi0.5Na0.5TiO3-xBaTiO3, and x is ranged from 0.03-0.09. The preparation method for the texturing piezoelectric ceramic material comprises the following steps: preparing base body material thin sheets, coating the surface of the base body material with the template material crystals to form the direction arrangement, stacking a plurality of thin sheets, and performing thermal press forming and sintering to obtain the texturing piezoelectric ceramic material. The preparation method is easy to operate, low in cost and suitable for large-scale industrial production; the prepared piezoelectric ceramic material is high in texturing degree, has the Curie temperature being more than 300 DEG C, is high in piezoelectric property and can be widely applied to the aspects of piezoelectric sensors, piezoelectric motors, high-precision displacement control and the like.
