SPECTROMETRIC STUDY OF THE THERMAL EVOLUTION OF MECHANOCHEMICALLY PREPARED HYDROXYAPATITE-BASED POWDERS

This study deals with the production of hydroxyapatite by a mechanoche mical method, especially following the transformations that are involv ed during their annealing when the physico-mechanical conditions of sy nthesis are more or less strong. In particular the higher the reacheab le crushing pressure during synthesis: the lower the presence of spuri ous phosphates during sintering. The main structure-related parameters were evaluated as a function of annealing temperature, and possible i nterpretations given thoroughly.
