Preparation and biological evaluation of si-substituted HA ceramics with controlled composition
Résumé
This work aimed at preparing dense and monophasic silicated hydroxyapatite ceramics over the range 0 <= x <= 1.0 mol of silicon. The synthesis of the powder via an aqueous precipitation process followed by an adapted thermal treatment showed that it was possible to obtain dense single-phased apatite ceramics containing up to 0.6 mol of silicon. The in vitro biological characterization of these materials was performed.
