Well dispersed Y 2 O 3 nanoparticles are prepared by azeotropic co‐precipitation method. (Ba 0.90 Ca 0.10 )(Ti 0.9 Sn 0.1 )O 3 lead‐free piezoelectric ceramics doped with the nano‐sized Y 2 O 3 (BCTZY, x = 0.01–0.09%) are synthesized at 1460 °C for 2 h via solid‐state sintering method. X‐ray diffraction suggests typical perovskite structure of all the compositions. The addition of the nano‐Y 2 O 3 results in the improvement in dielectric and piezoelectric properties. The optimized piezoelectric properties is obtained at x = 0.01 with d 33 of 596 pC/N and K p of 57.1%, respectively.
