摘要

The regularities of the influence of mechanical activation procedures on the processes of phase formation, formation of crystalline and grain structures, and electrophysical properties of ferro-piezoelectric material based on a three-component system of solid solutions (1-x) Pb(Ti0.47Zr0.53)O3-xPb(Nb2/3Zn1/3)O3 doped 1.5 mas. % Mn2O3 with x = 0.15 have been established. The durations of mechanical activation that give a high density of ceramic, its best dielectric, piezoelectric and ferroelastic parameters have been determined. It has been shown that the dependence of these parameters on the duration of mechanical activation confirms the known correlation relationship "elemental composition—internal structure (crystalline, grain, domain…) – macro-responses" realized in materials with special electrical properties (ferroelectrics). It should be noted that the extreme values of all the presented characteristics are realized under such technological regulations that ensure the extreme nature of the parameters of the internal structure of objects. In this respect, the best piezoelectric characteristics and mechanical quality are possessed by the studied ceramics mechanically activated for (10–15) minutes. A conclusion is drawn on the expediency of using the obtained data in the development of similar materials and devices based on them.
