Study on the Hydrothermal Reaction of Exchange of Porites Into Hydroxyapatite

Porous coralline hydroxyapatite (CHA) was produced by hydrothermal conversion of Porites skeleton (aragonite) at different temperatures and pH, with and without mineralizer KH2PO4respectively. 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
