Abstract: In this study, composite material consistsof silver (Ag) nanoparticles added to hydroxyapatite as matrixderived from bovine bone was prepared to investigate the possibility of using hydroxyapatite as bone substitute in high load bearing locations. The phase composition and structure of the sintered bio-ceramics composite were identified by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM-EDX), respectively. Densification rate of HA/Ag was assessed by measuring the density and apparent porosity. A mechanical properties of the sintered HA/Ag was carried out by technique of vickers indentations and compressive strength determinations. The results showed that the bioceramic composite present higher densification, better mechanical properties compared to pure hydroxyapatite.
