Abstract: Strontium substituted hydroxyapatite was synthesized by microwave induction，using SrCl₂，Ca(NO₃)₂ and (NH₄)₂HPO₄ as raw materials. The elemental composition of SrHAP was determined by the DHF82 immediate multiple-element analyzer and titration，while its phase composition was characterized with X Ray diffraction（XRD），and the granularity of the prepared powder was measured. The results showed that SrHAP could be prepared by microwave induction，whose elemental composition was close to strontium substituted hydroxyapatite by raw material stoichiometric calculation. With microwave induction，the crystallinity of SrHAP was improved with less time，and the structure of SrHAP was significantly affected by the amount of Sr. The SrHAP powder was also smaller than that prepared with conventional methods.
