“…The resin was then pre-calcined at 350 °C and, subsequently, subjected to a heat treatment at 1000 °C to obtain the BaSnO3 material. The powder obtained at the end of the synthesis processes was characterized by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) [16].…”

“…When the dispersion process was complete, the slip was poured into the mold. This mold was formed by taking 75 g of water per 100 g of gypsum (consistency 75) according to the requirements set by international standards [16]. The slip was poured into the mold and left until it reached the desired wall size, and then the piece was removed.…”

In order to build bulk pieces using the slip casting technique, barium stannate (BaSnO3) ceramic powders were synthesized using two chemical methods (controlled precipitation and Pechini). Differences in the electrical behavior of the pieces, depending on the synthesis method employed, were then determined. For the analysis, a stable suspension of the synthesized ceramic powder (or 57.6 % solids slip) was obtained using water as solvent; the slip was poured into a mold to produce parallelepiped shaped green pieces. The electrical behavior in air at 300 °C was determined for pieces sintered using a range of temperatures. The results of this electrical characterization showed that the method of synthesis has strong effects on the electrical behavior of the sintered samples.

“…To obtain BaSnO 3 with the Pechini method, a mixture of ethylene glycol and citric acid was first heated to 70°C, as indicated in a previous paper. 21 The precursors C 4 H 6 BaO 4 and SnCl 2 Á2H 2 O, in the amounts 8.4 and 7.4 g, respectively, were added to the ethylene glycol and citric acid solution. At room temperature, the resulting solution was brought to a basic pH and heated to 140°C, stirring constantly until a resin was formed.…”

This work aimed to study the influence of seven hybrid functionals (B3LYP, B1WC, B3PW, PBE0, PBESOL0, SOGGAXC, and WC1LYP) and selected basis sets in the CRYSTAL software library on the calculated structural, electronic, mechanical, and vibrational properties of BaSnO 3 under the framework of periodic density functional theory. Based on the results showing the best approximation of the experimental band gap energy and lattice parameter, the PBE0 functional and the Baranek basis set were used to optimize the outer valence shell functions, α sp and α d , in order to improve the quality of calculated properties. An analysis was done to determine the density of states, band structure, elastic constants, and infrared (IR) active modes. The results were compared with other reported quantum mechanical calculations and available experimental data.
