This research focused on the mechanical electrical and biological properties of magnesium doped (Mgx, x = 0.5 - 2.5 mol%) hydroxyapatite(Hap) using chemical method. It was observed that addition of magnesium produced the secondary phase (whitlockite) depended on the concentration of magnesium using the XRD, FTIR and Raman techniques. These two phases forming BCP(Biphasic) are beneficial from the implant point of view. The dielectric properties were measured as a function of frequency for different concentration of Mg. For 1.0 -2.0mol% doped Mg samples showed dielectric constant value within the range required for implant material. The bioactivity and However, beyond 2mol% of Mg third phase of magnesium oxide was also observed which enhanced the micro-hardness and bioactivity of specimen.
