Paper Title:
Effect of Al2O3 Addition on Dielectric, Piezoelectric and Ferroelectric Properties of 0.2Pb(Zn1/3Nb2/3)O3–0.8Pb(Zr1/2Ti1/2)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
