Summary: In this study, Dy3+-doped hydroxyapatite compound with a single phase hexagonal structure was successfully synthesized via co-precipitation method. The structural analysis confirmed the irregular morphology of the grains and the size range of 120-800 nm. Dielectric and electrical conduction studies revealed the dominant polarization mechanisms and the presiding conduction mechanism, respectively. The contribution of grains rather than grain boundaries in the conduction phenomena was observed in the Nyquist plots. A.C conductivity analysis identified hydroxyl (OH-) and oxygen (O-2) ions as the main charge carriers responsible for conduction in hydroxyapatite compounds.
