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.

摘要： 以SrCl₂、Ca(NO₃)₂和(NH₄)₂HPO₄为原料，采用微波法合成了掺锶羟基磷灰石。对制备的SrHAP进行元素含量分析，采用XRD对其结构进行了表征，并测定粉体产物的粒度。研究结果表明：采用微波法可以制备出元素组成接近原料计算化学计量比的掺锶羟基磷灰石；采用微波法可以快速得到结晶性好的SrHAP；掺锶量对微波合成的SrHAP的结构有显著影响；微波法比常规方法制备出的SrHAP粉体的粒度小。
