✦ Synopsis
The order of the cubic tetragonal phase change in ferroelectric Pb(Zr x Ti 1؊x )O 3 (PZT) was investigated by measurements of the specific heat. The specimens studied were highly crystalline powder samples carefully prepared by chemical synthesis methods to ensure chemical homogeneity. The existence of a tricritical point in the compositional range 0.304x40.40 was established. The results demonstrated a close correspondence between the effects of hydrostatic pressure and the effects of zirconium substitution on the order of the transition. A relationship between the first-order character of the transition and the ionic packing density in the cubic structure was proposed.
