(Bi1-x La x )FeO3 (0.00 ≤ 0.06) ceramics have been synthesized through a mixed oxide route to investigate their structural, morphological, optical, dielectric, and magnetic properties. All the samples are revealed be in rhombohedral structures along with R3c space group 161 number. A high relative permittivity lowest tangent loss observed BLFO at frequency range 1-100 MHz. The optical studies show that excitation energy increases increasing content. Moreover, magnetization being strongly...
Owing to their outstanding performance, environmental friendliness and stability, perovskite materials are becoming very important for solar cells, renewable energy sources thermoelectric generators. This work uses the first-principles approach explore structural, electronic, optical elastic characteristics of K2ScCuF6 K2YCuF6 double perovskites. The negative formation in Birch-Murnaghan confirms stability compounds Fm3m (2 2 5) space group. analysis electronic properties concluded that both...
The Mg-based dielectric ceramics of (Bi0.5Na0.5)(1−x)MgxTiO3, 0.00 ≤ x 0.04 was successfully synthesized by mixed oxide route at 850 °C for 2 hrs. XRD result revealed the single phase monoclinic crystal structure without any secondary phases. SEM image shows uniform grain size, low porosity and denser microstructure samples. grains size gradually increases from 1.58 µm to 2.70 due mass transportation during sintering process. EDX analysis spectra all samples investigated reported peaks...
The low-temperature sintering of (Bi0.5Na0.5)TiO3-based ceramics can be achieved by aid CuO. Piezoelectric (1 – x)[0.90(Bi0.5Na0.5)TiO3 0.10SrTiO3] xCuO (BNT-ST-Cu) with x = 0, 0.01, 0.02, 0.03, and 0.04 were prepared through the mixed oxide route. A tetragonal structure was indexed for undoped sample. Its found to changed a pseudocubic when Cu added. For samples, temperature (Ts) sufficient densification 1160 °C. However, Ts reduced 1090–1120 °C Cu-added specimens. Field emission scanning...
Pleasant interior conditions within cars, as well a comfortable feeling, are primary needs of car drivers to perform vital body functions during driving. In cooler outer environment, warming system seats can quite feasibly maintain realistic thermal balance in the body. An inbuilt heating not only provide adequate heat driver but is also relevant minimizing energy consumption vehicle interior. order evenly distribute over contact area automotive seats, conductive textiles proposed. fact,...
Preparation of a lead-free system (Ba0.8Ca0.2)TiO3-xBi(Mg0.5Ti0.5)O3 (BCT-BMT) with x = 0, 0.1, 0.2, 0.3, 0.4, and 0.5 was carried out using solid-state reaction technique. X-ray (XRD) diffraction analysis confirmed tetragonal structure for which shifted to cubic (pseudocubic) at ≥ 0.1. From Rietveld refinement, single phase symmetry model (P4mm) observed however, sample 0.1 0.5, the data are modeled (Pm3m). Composition 0 showed prominent Curie peak, typical ordinary ferroelectrics...
