Abstract

Hydroxyapatite powders were prepared by the solgel reaction starting from Ca(NO3)2·4H2O and H3PO4. Xray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG) and differential thermal analysis (DTA) were employed to characterize the process of solgel transition. The results obtained indicate that the initial concentration of Ca(NO3)2 and sintering temperature have important effects on structural features. 
