N2 - The enthalpies of formation of some AFm phases of the type Ca2Al (OH) 6X.xH2O (X = Cl-, Br-, I-, NO3-, ClO4-, ClO3-,BrO3-and IO3-) were determined by measuring the heats of solution in hydrochloric or perchloric acid. From the differences between the heats of solution of the compounds and their dehydration products, the enthalpies of dehydration were established. They increase with increasing enthalpies of hydration of the individual anions X in aqueous solution. However, this relationship is not the same for halide ions as for oxy-anions.
