| Abstract | ||
| The parameters required for the preparation of stiochiometric hydroxyapatite (HAP/ Ca10(PO4)6(OH)2) with biological Ca/P ratio 1.67 was carried out by using wet chemical method which refers to the drop wise addition of (NH4)2HPO4 to Ca (NO3)2 solution. The effect of intrinsic factors like those that pH, reaction temperature, ageing, digestion time and sintering temperature on the synthesis of HAP powders were studied and then the powder were characterized by analytical and spectral techniques. The method is indicating the formation of crystalline HAP with no major decomposition peaks and absence of impurities by close control of the all process parameters. | ||
