Some Examples Of The Application Of Thermochemistry
titative thermochemistry, based on nu-merical data, apparently has a wide field of possible application to petrology, it has been used very little as yet for solv-ing petrological and mineralogical prob-lems. The reason for such a circumstance is revealed by the fact that calorimetric data for natural or artificial minerals are scanty.
Thermochemistry An Overview Sciencedirect Topics
Thermochemistry is defined as the branch of thermodynamics that focuses on changes occurring during chemical reactions. For thermochemical purposes, chemical reactions are understood to include not only the reactions in which the products have a different chemical composition than the initial reactants, but also those reactions that result in a ...

Portland cement clinker thermochemistry. A wide range of temperature values are found in the literature. Despite the importance of the reaction, the state of knowledge is still poor, perhaps because it is difficult to determine equilibria in a reaction that is not smoothly reversible, and also because of the extraordinary difficulty in getting calcite samples of adequate purity.
