“…[51] For this optimization, thermodynamic data for the liquid and solid phases, invariant reactions and liquidus/solidus were used, and optimization was done according to Schmid-Fetzer et al [52] guideline, similarly to previous works. [19,20,53,54] Each piece of the selected information was given a certain weight based on experimental uncertainty. The optimization was carried out step by step.…”

“…Since gallium can be used as one component, there is also a need to create thermodynamic database of binary gallium alloys which can contribute to multicomponent systems. Consequently, we analyzed recently silver-gallium [19] and copper-gallium [20] binary alloys. As far as the Au-Ga binary system is concerned, it was already optimized twice, but under different assumptions.…”

Activities of gallium in the liquid Au-Ga alloys were determined using galvanic cells with the solid oxide electrolyte. The cells of the type:were used in the temperature range from 1050 to 1273 K, and for four alloy compositions x Ga = 0.2, 0.4, 0.6 and 0.8. From the measured e.m.f.'s the activity of gallium was derived, which taken together with the recently measured heat of mixing provided precise description of the thermodynamic properties of the liquid phase. This study was supplemented with DTA experiments which were performed for three alloy compositions, namely 0.15, 0.25 and 0.40 gallium mole fraction. The results of these experiments verified with temperature of respective invariant reactions. Finally, present results, taken together with the information existing in the literature, were used for the calculation of the optimized Au-Ga phase diagram. ThermoCalc software was applied to complete these calculations.

a b s t r a c tPhase diagram of the AgeBieGa ternary system was investigated using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and x-ray powder diffraction (XRD) methods. Experimentally obtained results were compared with the results of thermodynamic prediction of phase equilibria based on calculation of phase diagram (CALPHAD) method. Phase transition temperatures of alloys with overall compositions along three selected vertical sections AgeBi 50 Ga 50 , BieAg 50 Ga 50 and GaeAg 50 Bi 50 were measured by DTA. Liquidus temperatures were experimentally determined and compared with the results of thermodynamic calculation. Identification of coexisting phases in samples equilibrated at 200 C was carried out using SEM-EDS and XRD methods. Obtained results were compared with the calculated isothermal section of the AgeBieGa ternary system at corresponding temperature. Calculated liquidus projection and invariant equilibria of the AgeBieGa ternary system were presented. The obtained values were found to be in a close agreement.

Bismuth sulfide (Bi2S3) with micro/nanostructures as an important semiconductor material has attracted considerable attention due to its high ionic conductance, high photoelectric conversion efficiency, and large absorption coefficient, which is widely applied in the areas of photocatalysis, energy conversion, sensors, biomedicine, and pollutant disposal. Up to now, various strategies are reported for the morphology‐controlled synthesis of micro‐nanoscale Bi2S3 and Bi2S3‐based materials via manipulating the thermodynamics and kinetics in the chemical fabricating process. However, the Bi2S3 with designed shapes still remains to be developed to well adapt these diverse usages. To conclude, the designed preparation strategies, advanced applications, current challenges, and future expectations of Bi2S3 are discussed to provide some potential suggestions for further promotion of Bi2S3 functional materials.
