【摘要】 分别在不同的反应温度、不同的 pH值、加矿化剂与否的条件下 ,将滨珊瑚水热转换为珊瑚羟基磷灰石。利用X射线衍射 (XRD)、扫描电子显微镜 (SEM )分别对产物和中间产物的物相和微结构进行了分析。发现不同条件下存在有不同的反应路径。考察了反应温度、pH值和矿化剂对珊瑚水热反应的影响。更多还原

【Abstract】 Porous coralline hydroxyapatite (CHA) was produced by hydrothermal conversion of Porites skeleton (aragonite) at different temperatures and pH, with and without mineralizer KH 2PO 4 respectively. X-ray Diffraction Analysis (XRD) and Scanning Electron Microscopy (SEM) were employed to characterize the phase composition and structure of products prepared under different conditions. The influences of temperature, pH and mineralizer on the hydrothermal exchange of porites into coralline hydroxyapatite were investigated.更多还原
