| 摘 要： | 以表面活性剂为模板的介孔材料合成方法广为人们关注．以十二烷基磺酸钠(SDS)为模板,在水性体系中制备了层状介孔磷酸钙盐．用XRD表征了合成产物的无机相组成和层状结构的有序度．考察了不同熟化时间下SDS、磷源和乙醇的影响．结果表明,SDS用量增加可以提高层状结构的有序度,磷酸铵盐特别是(NH_4)_2HPO_4为磷源、乙醇与水体积比为1：1对有序层状结构的形成最有利．

| Abstract: | Lamellar calcium phosphates were synthesized by sodium dodecyl sulfonate(SDS,C_(12)H_(25)SO_3Na) as templates in aqueous media.Composition of inorganic phases and order degree of lamellar structure were characterized by X-ray diffraction(XRD).Influence factors under different riping times,such as SDS,phos- phorus sources and ethanol,were studied.The results show that the order degree of lamellar structure is im- proved with the increase of SDS,and ammonium phosphates,especially(NH_4)_2HPO_4 as phosphorus sources and volume ratio of ethanol to water 1:1 benefit the forming of the ordered lamellar structure. |
