Abstract
A phase diagram based on dielectric‐permittivity‐versus‐temperature measurements and high‐temperature X‐ray diffractometry was proposed for 0.4Pb(Ni1/3,Nb1/3)O3‐xPbZrO3‐(0.6‐x)PbTiO3(0.2 lessthan equal toxlessthan equal to 0.32) relaxor‐ferroelectric solid solution, and a morphotropic phase boundary that sharply bends toward zirconium‐rich compositions was found. A spontaneous normal‐to‐relaxor ferroelectric transition was also observed when heating was performed for all the compositions tested near the morphotropic phase boundary. Additional considerations about previously published phase diagrams for Pb(Zn1/3,Nb2/3)O3‐PbTiO3and Pb(Mg1/3,Nb1/3)O3‐PbTiO3might lead to an extension of the presented diagram to these compositions.Keywords
