摘要
为探索制备无定形磷酸钙(ACP)的新方法.采用共沉淀法,在甲醇溶剂中,使用Ca(NO3)2和(NH4)2HPO4作为原料,一步反应制得无定形磷酸钙.产物经FTIR表征,具有无定形磷酸钙的特征红外吸收;经XRD表征,具有典型的无定形磷酸钙衍射峰.制得的无定形磷酸钙在空气和有机溶剂中都有较好的稳定性.
The purpose of this paper is to explore a new method to synthetize amorphous calcium phosphate（ACP）.In methanol,using Ca（NO3）2 and（NH4）2HPO4 as materials,ACP is synthetized by a single step through coprecipitation method.The product is characterized by FTIR and XRD.FTIR shows characteristic absorption peaks of ACP and XRD show characteristic peaks of ACP.The results above indicate that the obtained product is ACP which is stable in air and organic solvent.
