A thermoanalytical, morphological, and structural study of fluoridated calcium phosphates that were prepared by different
variants of a synthesis in anhydrous alcohols is reported. The obtained materials were neither fully amorphous nor single-phased
crystalline, and their nature considerably depended on the synthesis conditions. In all cases, the retention of significant
amounts of solvent in the solid product was observed. A complete removal of the solvent was only possible by heating to temperatures
above ~573–673 K which resulted in variations in the elemental composition, phase changes, and an increase of the crystallinity.
Consequently, this synthesis in anhydrous alcohols is not a viable route to obtain materials with a defined crystallinity
