Abstract

Language:

This study investigates the superambient heat capacities of synthetic stibnite, berthierite, and chalcostibite to revise their thermodynamic properties and elucidate the implications for phase equilibria. The primary objective was to enhance the understanding of these important antimony-bearing minerals, which are significant both as ores and in various geological contexts. Methodologically, we employed advanced calorimetric techniques to obtain accurate heat capacity data over a range of temperatures, and subsequently integrated this information with existing thermodynamic models. The results indicate revised heat capacities that show a marked deviation from previously reported values, suggesting new insights into the mineral stabilization at high temperatures. Additionally, these findings have critical implications for predicting phase behavior in antimony deposits, which can aid in the exploration and processing of these resources. The improved thermodynamic parameters also contribute to the broader understanding of mineral interactions and stability under varying geological conditions.
