The synthesis of calcium-silver hydroxyapatites of composition Ca10-xAgx(PO4)6(OH)2-xx is discussed, together with their physical and chemical properties. Samples prepared both by dry process and by double decomposition were characterized using a variety of analytical techniques (chemical analysis, X-ray diffraction, infrared spectroscopy). The lattice parameters a and c increase linearly with the amount of silver added. The increase is attributed to the preferential substitution of the silver ion in site Me (I) of these apatites.
