Summary: 0.57(Bi0.8La0.2)FeO3-0.43PbTiO(3)-x mol%Fe2O3 ceramics (BLF-PT-xFe, x = 0, 0.025, 0.05, 0.125, and 0.25) were prepared by the solid-state reaction method. Fe doping improves the insulation properties and increases grain size. The Curie temperature remains constant with Fe content, while depolarization temperature increases. Second ionized oxygen vacancies act as major carriers in the temperature range of 200°C-500°C. The optimal composition is x = 0.05, with low dielectric loss, high AC resistivity, and piezoelectric coefficient.

Summary: Ceramic samples of the (1-x)Ba(Ti0.50Sn0.50)O-3•xPbTiO(3) system were synthesized by solid-state reaction. The samples exhibit solid solutions with perovskite structure throughout the composition range, with symmetry changing from cubic to tetragonal with increasing PbTiO3 content. Different dielectric responses are observed depending on the PbTiO3 content, transitioning from relaxor ferroelectric to ferroelectric-like with a diffuse phase transition, and finally to usual ferroelectric response.

Summary: (1-x)Pb(Mg1/3Nb2/3)-xPbTiO(3) (PMN-xPT) ceramics were synthesized by solid-state reaction method. The structure, dielectric and ferroelectric properties were investigated. As x increases, PMN-xPT transitions from a cubic to a rhombohedral phase, enhancing the ferroelectricity. The electrostrain and longitudinal electrostrictive coefficient Q(33) increase and then decrease within a critical temperature region, indicating strong temperature-dependent characteristics. A maximum Q(33) of 0.0361 m(4)/C-2 was obtained at x = 0.2, and a phase diagram of the system was constructed. The findings provide insights into the phase evolution in this system and demonstrate a temperature-dependent electrostrictive effect that can be utilized to enhance electrostrains in PMN-based solid solutions by regulating the critical temperature region using engineering strategies.

Summary: Modern technologies drive the research on multicomponent nanosized materials with improved properties, which are determined by the atomic arrangement and interphase interactions. In this study, we investigated the formation of solid solutions in Ag-Cu nanoparticles across a wide size and temperature range using in situ TEM techniques. Our results provide insights into the mixing patterns and composition of phases in AgCu nanoparticles at the atomic level and construct the solid-state part of the Ag-Cu phase diagram for nanoparticles as small as 5 nm. We observed an asymmetric behavior of the solvus lines, with the content of Cu in Ag increasing with decreasing size, and a size-dependent terminal temperature Tterm for the existence of AgCu alloy nanoparticles in a vacuum.

Summary: Samples in Si-Al-R-O-N systems were prepared by solid-state reactions, and X-ray diffraction was used to investigate the formation of RAM-J(R) solid solutions. Phase relations between RAM, J(R) and RSO at 1700 degrees C were summarized in a phase diagram, revealing the formation of continuous solid solutions along specific tie-lines. The established phase relations may aid in selecting compositions for developing monolithic ceramics or composites in SiC/Si3N4 systems.

Summary: This paper investigates the dielectric spectra of solid solutions in the (1 - x - y)NaNbO3-xKNbO(3) -yCdNb(2)O(6) system at different temperatures. It is found that as the content of KNbO3 increases, the local maximum of the system gradually blurs and becomes an inflection point. The measurements show that the maxima of the frequency-dependent electric field shift within certain temperature ranges, which may be related to crystallographic disorder.

Summary: This paper presents a study on the microstructure and dielectric properties of solid solutions in the (1-x)BiFeO3 - x/2 PbFe1/2Nb1/2O3 - x/2 PbFe2/3W1/3O3 system with x = 0.05 to 0.50. X-ray diffraction analysis is used to analyze the studied system and obtain the phase diagram at room temperature. The influence of oxygen defects and liquid phase on the structure and microstructure of the samples is critical. The studied solid solutions exhibit relaxor behavior, which is associated with the movement of oxygen vacancies and the occurrence of Maxwell-Wagner relaxation.
