Abstract Two-stage solid-phase synthesis followed by sintering according to the usual ceramic technology prepared high-density solid solutions of the composition ( Pb 1 − α 1 − α 2 Sr α 1 Ba α 1 ) [ Ti x Zr y ( Nb 2 / 3 Zn 1 / 3 ) ( Nb 2 / 3 Mg 1 / 3 ) 1 − x − y ] O 3 , with α1 = 0.02 ÷ 0.12; Δα1 = 0,02, α2 = 0.0036 ÷ 0.073; x = 0.385 ÷ 0.430, y = 0.402 ÷ 0.447. The laws governing the formation of the crystal structure, grain landscape, macroresponses (dielectric, piezoelectric, ferroelastic) and correlation links between them have been established. A group of solid solutions with promising electrophysical parameters for low-frequency applications was identified. The conclusion about the expediency of taking into account (accounting) the results obtained in the development of low-frequency devices (hydrophones, microphones, seismic receivers, etc.) was made.
