| Abstract: | By using P2O5, Ca（NO3 ）2·4 H2O as crude materials, and using absolute alcohol as solvent, the resultant gel precursors was obtained by adjusting pH. Nano-rod crystal powders of hydroxyapatite （HAP） were prepared by sol-gel synthesis and hydrothermal treatment. The phase composition and morphology of the combustion products and the powder by hydrothermal synthesis were investigated by XRD, FTIR and SEM. The mechanism of the phase crystal form was also analyzed. Results showed that the composition of the main crystal phase of the precursor powder prepared by sol-gel/hydrothermal treatment was Nano-rods HAP（100 × 1 800 nm）. |
