Notes:
A novel synthesis of nano-fluoride-substituted hydroxyapatite (nano-F-HAP) wassuccessfully realized through dialysis process within 4 h, which required much shorter time than the methods reported so far. In new preparation, a dialysis was employed to purify unwanted ions. The removal efficiency of impurity ions in dialysis was evaluated by calculating the concentration of the representative irons NH4+ between the inner slurry and outer distilled water. Results showed thattotal dialysis efficiency came to 94.5%. The final products were characterized by XRD, HR-TEM, and FT-IR. The XRD and FT-IR results strongly supported substitution of F- for OH-, and the TEM pictures further indicated that the final crystals are about 100nm in length and about 20 nm in diameter without obvious aggregation. Therefore, comparing with traditional purifying processing,such a new synthesis provides a promising application for scale preparation of fine nano-F-HAP crystals
