Understanding the thermodynamic stability of materials plays an essential role in their applications. The high-temperature oxide melt solution calorimetry is a reliable method developed to experimentally measure formation enthalpy. Until now, it has been mostly used for the characterization of oxide materials. We introduce modifications in the experimental technique which makes it suitable for a wide range of non-oxide compounds. The modified methodology was used to measure the heat effects associated with the oxidative dissolution of almost all p-elements of groups III, IV, V, and VI and verified by calculating the standard enthalpies of formation of the corresponding oxides at 298 K. The results presented serve as a compelling database for pure p-elements, which will provide a very straightforward way of calculating the formation enthalpies of non-oxide systems based on high-temperature calorimetric experiments.

了解材料的热力学稳定性在其应用中起着至关重要的作用。高温氧化物熔体溶液量热法是一种可靠的方法，用于实验测量地层焓。迄今为止，它一直主要用于氧化物材料的表征。我们对实验技术进行了修改，使其适用于各种非氧化物化合物。修改后的方法用于测量与III，IV，V和VI组的几乎所有p元素的氧化溶解相关的热效应，并通过计算在298 K下形成相应氧化物的标准焓来验证。展示了作为纯p引人注目的数据库-元素，这将提供基于高温量热实验计算非氧化物系统的生成焓的非常直接的方法。
