In order to improve the electrical and mechanical properties of 0.02Pb (Y1 / 2Nb1 / 2) O3-yPbTiO3- (1- 0.02-y) PbZrO3 piezoelectric ceramics, the authors investigated the effect of various common additives on the electrical properties and mechanical properties of 0.02Pb Y1 / 2Nb1 / 2) O3 -yPbTiO3 - (1-y- 0.02) PbZrO3 ternary piezoelectric ceramics were investigated. The effects of different sintering temperatures on the properties of the materials were discussed. The experimental results show that Sr2 + and Ba2 + can increase the electromechanical coupling coefficient (kp, k33, kt) of 0.02Pb (Y1 / 2Nb1 / 2) O3 -yPbTiO3 - (1- 0.02- ), Dielectric constant and piezoelectric coefficient, and mechanical quality factor Qm; and adding 0.02Pb (Y1 / 2Nb1 / 2) O3-yPbTiO3- (1- 0.02- PbZrO3 will improve the mechanical quality factor of the material, meanwhile it will also damage the dielectric and piezoelectric properties and reduce the elastic compliant coefficient, which reflects the general characteristics of the hard additive. The annealing of 0.02Pb (Y1 / 2Nb1 / 2) O3 - yPbTiO3- (1- 0.02- y) PbZrO3 piezoelectric materials have a role in promoting.
