Study of structure and dielectric properties of Pb(Sn,Zr,Ti)O3 solid solutions

Results of investigation of Pb(Sn,Zr,Ti)O3 solid solutions are presented. It is shown that in the above-mentioned solid solutions at room temperature ferroelectric and antiferroelectric phases coexist. In this range dielectric properties have clearly pronounced anomalies. Phase transition from ferroelectric to antiferroelectric state of polarized materials under the effect of hydrostatic pressure occurs spasmodically. The value of ferroelectric-antiferroelectric phase transition depends on titanium concentration
