Synthesis of hydroxy-chlorapatites solid solutions

abstract

A series of chlorine substituted hydroxylapatites (HAP) were prepared through aqueous precipitation method. Characterization studies from XRD, elemental analysis and FT-IR spectra have confirmed the incorporation of added chlorine into the apatite structure forming solid solutions. The cell parameters for chlorine substituted hydroxylapatites underwent a significant expansion trend with increasing amounts of added chlorine that has replaced the hydroxyl group of HAP. However, the measured density values did not follow a clear trend with increasing amounts of chlorine incorporated in the apatite structure. (c) 2005 Elsevier B.V. All rights reserved.
