Abstract：Nano-Al2O3/HA composite powders were synthesized by chemical precipitation method, and the nano-Al2O3/HA composites were prepared by hot pressed sintering.The influence of F adopting on the structure and properties of nano-Al2O3/HA composites were studied.The research showed that mechanical properties of the Al2O3/HA composites could be improved by F doping, The bending strength and fracture toughness were 147.2 MPa and 2.19 MPa·m-0.5 when the F content was 1 and the decomposition of HA could be inhibited with F addition.What''s more, the obtained AlF3 phase could promote the densification process of composite ceramics.F doping can improve the bioactivity of the composite ceramics, but the F content has little effect on the bioactivity of the composite ceramics.
