Doped hydroxyapatites with enhanced physical, chemical, mechanical and physiological stabilities have received significant attention as bone substitute materials, bone tissue engineering, orthopedics etc. Fe doped hydroxyapatite bio-ceramic material has been successfully synthesized fromegg shell for the first time by wet chemical precipitation method. (NH4)2HPO4 was used as the source of phosphate. Two different concentrations of doping solution were chosen to synthesize the doped apatite and the developed apatite was characterized by using FTIR, XRF, XRD and SEM techniques. Observed data were in excellent agreement with the standard values for hydroxyapatite which indicated that the change in concentration of doping solution did not affect the characteristics of the doped apatite.
