N2 - In this study, Ag doped hydroxyapatite (HA) samples prepared by EDTA chelate decomposition method were characterized with X-Ray Diffraction Spectroscopy (XRD), Scanning Electron Microscopy (SEM) and antimicrobial sensitivity test. Hydroxyapatite (Ca 10(PO) 6(OH) 2) and NaCaPO 4 (rhenanite) phases were observed while Ag was present in the form of Ag 2O. Results showed that microstructurally controlled HA-based composites with NaCaPO 4 interphase can be prepared, which significantly enhances sinterability of hydroxyapatite at 1100°C without formation of any undesired second phases, such as tricalcium phosphate (TCP) known to decrease the stability of HA. The antibacterial sensitivity was tested with E.Coli gram-negative bacteria. The radius of circle enclosing the sample increases with increasing Ag content in the structure as an indication of the region of non-bacterial activity.
