Formation of calcium hydroxyapatite with high concentration of homogeneously distributed silver

In this study for the synthesis of silver-doped calcium hydroxyapatite (Ca-10(PO4)(6)(OH)(2):Ag; CHAp:Ag) an environmentally friendly aqueous sol-gel processing has been suggested. The sinterability and morphological properties of silver-activated calcium hydroxyapatite were investigated in the present study. The calcium hydroxyapatite doped with high concentration of silver (up to 10 wt %) has been prepared. This simple synthetic approach offers a feasible way to obtain highly homogeneous silver-doped CHAp bioceramics with possible application in medicine. The synthesis products were characterized using X-ray powder diffraction (XRD) analysis, infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The content of Ca, P and Ag in the synthesis products was determined by SEM (EDX).
