Full TextAbstract
In this work, Fluorohydroxyapatite (FHA) nanopowders were synthesized using nonalkoxide sol-gel method. Here calcium nitrate tetrahydrate Ca(NO3)2.4H2O, phosphorous pentoxide (P2O5) and ammonium fluoride (NH4F) were used to provide Ca-precursor, P- precursor and fluorine reagent, respectively. The FHA powders were calcined at temperatures ranging from 500 to 800ºC. The resultant products have been confirmed to be FHA (apatite phase) using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The thermal stability of FHA powders was studied through diffraction thermal analysis (DTA) and the optimized calcination temperature was found to be 600ºC. The results of transmission electron microscopy (TEM) and Debye-Scherrer equation have shown that the sizes of the FHA particles were in the range of nano-scale.
