Evolution of the macroresponses during the transition from two-to six-component systems of the solid solutions with fundamentally different properties

Abstract

The solid solutions (SS) of the n-component (n = 2 … 6) systems with the participation of two fundamentally different bases – (Na, K)NbO3 (NKN) and Pb(Ti, Zr)O3 (PZT) have been prepared by the two-stage solid-phase synthesis followed by the conventional sintering ceramic technology. Evolution trends of the structural and electrophysical parameters at such a complication of the compositions have been established. It is shown that with an increase in the number of the components in the systems, the spontaneous deformation, characterized by a uniform deformation parameter, δ, decreases, which, due to the existing correlations, leads to a decrease in the Curie temperature and an increase in the relative permittivity. The extreme “behavior” of the piezoelectric characteristics is associated with the competing influence of the permittivity and remanent polarization on them. A conclusion is made about the expediency of using the obtained results in the creation of similar materials and devices based on them.
