Abstract

Pure and Cu2+ doped nanohydroxyapatites were synthesised by a precipitation method to investigate the effect of Cu2+ ions on the structure of hydroxyapatite (HA) and its thermal stability after the air sintering at 1100 degrees C. A small amount of CaO was observed in the Cu2+ doped HAs after the X-ray diffraction results. The addition of Cu2+ changed the hexagonal lattice parameters of the HA and resulted in smaller grain size after sintering at 1100 degrees C. The addition of Cu2+ ions into HA resulted in smaller grain sizes (between 282 and 248 nm).
