摘要

在298 ~ 423 K的温度范围内，通过测量液体电解质的电动势，研究了锑化铁的热力学性质。利用Fe-Sb体系中FeSb2 + Sb和FeSb + FeSb2两相区域的平衡样品进行测量。采用粉末x射线衍射法测定了样品的相组成。计算了铁在合金中的偏摩尔函数，以及化合物FeSb和FeSb2的标准生成热力学函数和标准熵。将所得结果与已发表的文献结果进行了比较分析。

Thermodynamic study of iron antimonides by electromotive force measurements

Thermodynamic properties of iron antimonides were investigated by measuring the electromotive force with a liquid electrolyte in the temperature range of 298–423 K. The measurements were performed using equilibrium samples taken from the two-phase regions FeSb₂ + Sb and FeSb + FeSb₂ of the system Fe—Sb. The phase composition of all the samples was monitored using powder X-ray diffraction. The partial molar functions of iron in alloys, as well as the standard thermodynamic functions of formation and the standard entropies of compounds FeSb and FeSb₂ were calculated. A comparative analysis of the obtained results and those found in published works was carried out.
