The present study reports a relatively simple method for the synthesis of stable silver substituted hydroxyapatite nanoparticles with controlled morphology and particle size. In order to achieve this, CTAB is included as a surfactant in the microwave refluxing process (600W for 7min). The nanoparticles produced with different silver ion concentrations (0.05, 0.1 and 0.2wt%) were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscope (FESEM), energy dispersive X-ray (EDX) and Brunauer–Emmett–Teller (BET) analysis. XRD and FTIR analyses reveal that the Ag-HA nanoparticles were phase pure at 1000°C. FESEM images showed that the produced nanoparticles are in the size range of 58–72nm and exert uniform elongated spheroid morphology. The dielectric properties suggest that the increase in dielectric constant (ɛ′) and …
