Thermodynamics of the Kaolinite-Group Minerals

摘要

The enthalpies of formation of kaolinite and dickite were determined by high-temperature melt solution calorimetry to be Δ_fH°(298.15 K) = -4118 ± 10 and -4127 ± 10 kJ/mol, respectively. These data represent the first calorimetric confirmation of the metastability of kaolinite with respect to dickite.
