摘要：

Hydroxyapatite (HAp) was synthesized through the decomposition of a Ca(EDTA) complex in presence of phosphate ions. Ion concentrations are much higher than previously reported. This route allows the formation of HAp at temperatures below 140 degreesC and at different pH values. Phase identification, crystallinity and morphology of the obtained products were studied via FTIR, SEM, XRD and EDS. (C) 2004 Elsevier Ltd. All rights reserved.
