Abstract :
The ternary oxide solution of lead zirconate titanate (PZT) with a complex perovskite oxide Pb(Zn/sub 1/3/Nb/sub 2/3/)O/sub 3/, (PZN), a composition that is near that of PbZrO/sub 3/, was prepared, and its phase transition behavior was investigated. An extension of the ferroelectric phase by the addition of PZN and a change of the transition between two ferroelectric phases from a first-order to a second-order nature are described.<>
