在OP乳化剂/异辛烷/正葵醇/((NH4)2HPO4溶液、Ca(NO3)2溶液及KF溶液)四元微乳液体系下合成氟磷灰石,采用扫描电镜(SEM),X射线衍射(XRD),红外光谱分析(FT-IR),电子能谱(EDS)等研究方法对不同pH条件下合成的氟磷灰石样品进行表征.结果表明:在弱碱条件下更利于氟磷灰石的合成,同时结晶程度更高；在pH=7.5条件下所制备氟磷灰石的Ca/P比约为1.62,与理论值(1.67)较为接近.%Fluoroapatite particles are synthesized in the quaternary microemulsion system containing OP emulsifier,isooctane,decanol,calcium nitrate,potassium fluoride and diammonium phosphate.SEM,XRD,FT-IR and EDS are used to characterize the morphology and structure of the different resulted samples under different pH circumstance.The results indicate that under the weak base condition,fluoroapatite is more advantageous to synthesize,and the crystallization is much higher.The Ca/P of fluoroapatite obtained by pH=7.5 is about 1.62,approaching to the theoretical value (1.67).
