Effect of Al₂O₃Addition on Dielectric, Piezoelectric and Ferroelectric Properties of 0.2Pb(Zn_1/3Nb_2/3)O₃–0.8Pb(Zr_1/2Ti_1/2)O₃ Ceramics

Abstract:

The structure and electrical properties of Al2O3-doped 0.2Pb(Zn1/3Nb2/3)O3-0.8Pb(Zr1/2Ti1/2)O3 ceramic, which is the morphotropic phase boundary composition of the PZN-PZT system, were investigated. The addition of Al2O3 content transformed the crystal structure rom coexisting with rhombohedral to purely tetragonal structure. Furthermore, addition of Al2O3 decreased r, d33 and kp, but increased Curie temperature and enhanced the mechanical quality factor. inally, the P–E and s-E loops demonstrated decreased Pr, Ec and strain level with addition of Al2O3
