Piezoelectric ceramic as well as preparation method and application thereof
The invention discloses piezoelectric ceramic as well as a preparation method and application thereof, and mainly relates to the field of piezoelectric ceramic. The method is different from a two-step sintering process of a traditional sintering process, and densified sintering of the KNN-based leadless piezoelectric ceramic is realized by effectively controlling the change of the sintering temperature and the heat preservation time and the formula of raw materials, so that the piezoelectric property of the KNN-based piezoelectric ceramic modified by BKLCH becomes more stable and excellent; according to the preparation method of the piezoelectric ceramic, complex sintering equipment such as hot pressing sintering and plasma sintering is not needed, sintering densification can be achieved through a common sintering furnace, the equipment cost is reduced, and industrial production is facilitated; besides, the piezoelectric ceramic provided by the invention can be applied to an optical fiber scanner in the field of laser display, and is particularly used for preparing an actuating part on the optical fiber scanner, and the actuating part utilizes the inverse piezoelectric effect of the piezoelectric ceramic to control an optical fiber on the actuating part to perform vibration scanning.
