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.
