(1-x) BCZT-xKNNLN lead-free piezoelectric ceramic
The invention discloses (1-x) BCZT-xKNNLN lead-free piezoelectric ceramic, and belongs to a piezoelectric ceramic material. The component formula is (1-x) (Ba0. 85Ca0. 15Zr0. 08Ti0. 92)-x (K0. 5Na0. 5NbO3-LiNbO3), wherein x is equal to 0, 0.1, 0.2, 0.3, 0.4 or 0.5, and the sum of the components is 100%. The preparation method comprises the following steps: burdening according to the component formula, and then carrying out ball milling, pre-sintering, secondary ball milling, spray granulation, tabletting forming, glue discharging sintering, silver printing and polarization. According to the ceramic, d33 is equal to 315pC/N, kp is equal to 0.46, epsilon r is equal to 1357, and tan delta is equal to 0.025; the preparation method is simple, has no special requirements on equipment, and is low in cost and small in environmental pollution. The piezoelectric ceramic material is a lead-free piezoelectric ceramic material.
