Structural Analysis and Characterization of Cu, Sr-doped Hydroxyapatite Whiskers

Abstract

Abstract.Cu and Sr ions doped hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 , HA) whiskers were synthesized by hydrothermal homogeneous precipitation method. The morphology, structure and the phase composites of the products were characterized by XRD, FTIR and SEM. The results showed that Cu 2+ or Sr 2+ partially substituted for Ca 2+ in the HA crystal, resulting in lattice distortion and lower crystallinity with Sr or Cu addition. For Cu-doped HA (Cu-HA) whiskers, the doping limit proportion should be below 8mol%, and for Sr-doped HA whiskers (Sr-HA), it was below 20mol%.
