| 摘 要： | 以尿素沉淀剂，运用溶液均匀共沉淀法制得纤维状羟基磷灰石(HAP)和无定形颗粒状守壳聚糖(CS)的复合粉体，通过水势处理调整纤维状HAP晶粒尺寸的大小，对粉体进行了XRD、TEM、IR及化学组成(Ca／P)表征。均匀一水热共沉淀过程中，pH值对粉体Ca／P、XRD、TEM、IR有很大影响。

| Abstract: | Using urea as the precipitant,the fibrous hydroxypatite(HAP)/chitosan (CS)composited powder was prepared with homogeneous co-oprecipitation,and the grain size of HAP was adjusted with hydrothermal treating(0.2MPa).The composited powder was characterrised by XRD,TEM and IR and chemical composition(Ca/P).In the course of homogeneous-hydrothermal co-precipitating,the pH value had great influence on Ca/P,XRD,TEM,and IR. |
