with Sol-gel method. In the first,

we gave the sol-gel process. Secondly, we make use of analytical methods of FTIR and XRD to analysis the

Hydroxyapatite precursor powder and the Hydroxyapatite precursor powders calcined at different temperature.

At last, the chemical mechanism of sol-gel synthesizing Hydroxyapatite were investigated through analyzing

the ethanol solution of P
