摘要

Ag-Au-Se-Te体系中矿物的标准吉布斯形成能是用加性元素贡献来计算的。在25℃和常压下，用选择程序（PC）计算了一摩尔贵金属和可变硫含量的初始状态下所考虑的系统的热力学平衡。模拟结果表明，银比金更积极地参与矿物组成。在一定浓度的硒和碲下，贵金属不会产生天然形式。

Thermodynamic Equilibria in the Ag–Au–Se–Te System at 25°C and Atmospheric Pressure

Standard Gibbs energies of formation for minerals of the Ag–Au–Se–Te system are calculated using additive elemental contributions. Thermodynamic equilibria of the considered system in the initial state of one mole of noble metals and variable chalcogen contents at 25°C and atmospheric pressure are calculated using the Selector program compleх (PC). Results from modeling show that silver participates more actively than gold in the composition of the minerals. Noble metals do not produce native forms at certain concentrations of selenium and tellurium.
