【 摘 要 】

Zn and Sr ions co-doped hydroxyapatite (Ca10(PO4)6(OH)2, HA) whiskers were synthesized by a hydrothermal homogeneous precipitation method. The morphology, structure and the phase composites of the products were characterized by XRD and SEM. The results showed that Zn2+ and Sr2+ partially substituted for Ca2+ in the HA crystal, resulting in lattice distortion and low crystallinity. When the doping ratio of Zn2+ in the solution containing Zn2+ and Sr2+ was more than 3 mol%, the shorter whiskers with low crystallinity appeared in the products.
