Structurization, Phase Rule Diagram, Relaxation Processes and Radio-Absorbing Properties of Solid Solutions Based on a Binary System BaNb2O6-SrNb2O6

Abstract

The investigation results of the processes of phase formation in barium niobate, strontium, and their solid solutions in the conditions of the variability of the thermodynamic background are presented. The formation of a grain landscape and dielectric properties (including relaxation phenomena) in the solid solutions of strontium niobate and their solid solutions and the establishment of regularities in the formation of radio-absorbing properties in them are studied.

Microwave Absorption Properties of Ceramics Based on BiFeO3 Modified with Ho

“…Therefore, it seems relevant to prepare BiFeO 3 modified with rare earth elements in a wide range of concentrations by solid-phase synthesis methods followed by sintering using conventional ceramic technology and to study its microwave absorption in the temperature range 300-520 K to establish the possibility of controlling its properties by thermal action. Since preliminary studies on BiFeO 3 modified with Dy, Ho, Tb [11] showed that SS BiFeO 3 with Ho have the best microwave absorption, the concentration range of the specified modifier was extended in this work.…”

“…The optimal conditions were selected, which ensured the homogeneity, high-density ceramic structure, and reproducibility of characteristics. Abubakarov et al [3] discussed phase formation in barium niobate, strontium, and their solid solutions (SSs) in the variable thermodynamic background conditions. The grain structure and dielectric properties, including relaxation phenomena, were studied.…”
