Results of the study of phase transitions in the system of solid solut
ions Pb-1-x(Li1/2La1/2)(x)(Zr1-yTiy)O-3 are presented. It is shown tha
t the coexistence of ferroelectric and antiferroelectric phases leads
to some peculiarities of the physical properties. The diffuseness of t
he paraelectric phase transitions is increased for solid solutions in
which these phases coexist, peculiarities of T-E phase diagrams take p
lace near the ferro-antiferro-paraelectric triple point, and the depen
dence of the dielectric constant on electric field are different from
those for traditional ferroelectrics.
