synthesis of fap, forsterite, and fap/forsterite nanocomposites by sol-gel method

The present study aims to investigate the preparation and evaluation of phase and morphological properties of a nano biocomposite ceramic. in this regard, the synthesis of fluorapatite (fap) as the first phase and forsterite considered as the second phase by the sol-gel method was taken into account. then, nanocomposites with the base of fluorapatite with 15, 25, and 35 wt% of forsterite were synthesized using the sol-gel method. the synthesized nanoparticles and nanocomposites were characterized by using different techniques, field emission scanning electron microscope (fesem), x-ray powder diffraction (xrd), and fourier-transform infrared (ft-ir) spectroscopy. x-ray diffraction test results as well as infrared spectroscopy indicated that fluorapatite, forsterite, and fluorapatite/forsterite nanocomposites were produced without impurity. fesem result showed that the particle sizes of the produced nanocomposites with 15, 25, and 35 wt% of forsterite ranged approximately between 25 and 80 nm. the result of the mtt assay proved the nontoxicity of samples for 7 days.
