✦ Synopsis

Pyrolytic routes previously developed for the formation of hydroxyapatite and calciumfluoride were modified and combined for the formation of hydroxyapatite/fluoroapatite solid solutions. Hereby phenyldichlorophosphine, calcium nitrate and calcium trifluoroacetate were used as starting materials. Hydrolysis and oxidation led to a polycondensation and enabled the formation of a viscous solution which, by means of drying, could be transformed to an amorphous solid. Calcining of this solid at temperatures up to 1100°C led to the formation of hydroxyapatite/fluoroapatite solid solutions.
