Thermodynamics of the kaolinite-group minerals

The enthalpies of formation of kaolinite and dickite were determined by high-temperature melt solution calorimetry to be ΔfH°(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.
