“…After that the relative permittivity decreased drastically. The dependent of relative permittivity on temperature phenomenon is similar to that reported in previous work, where the concentration of Fe 2+ ions is known to be very sensitive to temperature, and it increases as temperature increases [10]. It is known that the co-existence of Fe 2+ and Fe 3+ ions on equivalent crystallographic sites can give rise to an electron hopping conduction mechanism.…”

In this work, the complex perovskite Ba 0.9 Sr 0.1 [Ti 1-x (Fe 0.5 Nb 0.5 ) x ]O 3 (BST-FN) ceramic system with x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 were synthesized via a solid state reaction method. The ceramics were subsequently examined at room temperature by Xray diffraction using Cu K α radiation to identify the phase composition of each sample. The structures of the samples were found to be tetragonal and the tetragonality of which decreased with increasing the FN content. The relative permittivity and loss tangent were found to increase with temperature. The highest ε r was 2941 with the tan δ of 0.713 for x = 0.2 at room temperature and at 1 kHz.

“…Increasing tendency of ε is due to the increased conductivity in the samples caused by the presence of Fe 2+ in sintered BFN ceramics, as suggested by Ananta and Thomas [33]. The concentration of Fe 2+ ions is known to be very sensitive to temperature, and it increases as temperature increases [34]. It is known that the coexistence of Fe 2+ and Fe 3+ ions on equivalent crystallographic sites can give rise to an electron hopping conduc- tion mechanism.…”

“…While synthesizing a pyrochlore phase is formed besides the perovskite and its presence decreases the PFN ceramics properties. A two-stage columbite method was selected as a production method to limit the pyrochlore phase formation [13] [14]. At this stage an admixture in a form the Cr 2 O 3 chromium oxide (x from 0.01 to 0.06) was added to the solution.…”

An aim of this work was to determine an influence of an admixture, the chromium (for x from 0.01 to 0.06), on the mechanical properties of the PFN ceramics. The ceramics with chemical composition Pb(Fe0.5-xCrxNb0.5)O3 was synthesized in two steps from simple oxides PbO, Fe2O3, Nb2O5, Cr2O3. The first stage was based on obtaining the FeNbO4 from the Fe2O3 and Nb2O5 simple oxides. At this stage an admixture in a form the Cr2O3 chromium oxide was added to the solution. In the second stage the PbO lead oxide and the doped FeNbO4 (obtained earlier) were synthetized. The sintering of ceramic samples PFCN type was carried out by free sintering method. Temperature measurements of the internal friction were conducted on a computer-controlled automatic resonant mechanical spectrometer (heating cycle with 3 deg/min).
