  ABSTRACT: Effect of SiO2 addition on the microstructures of calcium-deficient hydroxyapatite prepared by the heat-treatments was examined. Obtained hydroxyapatites substituted with Si ion were characterized by XRD, FT-IR and XAFS measurements. XANES results of Si K-edge and P K-edge in these modified hydroxyapatites indicated the shift of peaks of P K-edge with the SiO2 contents, although no change of Si local structures. In this study, the effect of Si ion on micro- and local structure of hydroxyapatite with SiO2 addition was mainly clarified.
