Effect of High Temperatures on the Microstructure and Properties of Fluorine-Containing Hydroxyapatite-Based Materials

— This paper examines the feasibility of improving the strength of hydroxyapatite prepared by precipitation from solution via partial substitution of fluoride ions for hydroxyl groups and the addition of calcium fluoride. A comparative analysis of the resultant materials is carried out using advanced physicochemical characterization techniques. Fluoride ions are shown to influence the thermal stability, sintering behavior, microstructure, and strength of ceramics produced using precipitated hydroxyapatite.
