Effect of Al2O3 addition on dielectric, piezoelectric and ferroelectric properties of O.2Pb(Zn1/3Nb2/3)O 3-0.8Pb(Zr1/2Ti1/2)O3 ceramics
The structure and electrical properties of Al2O 3-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 from coexisting with rhombohedral t...
