Effect of Aging Time on Synthesis of Sol-Gel Derived Bioglass-58S Nanopowders

The aim of this research is synthesis of bioglass-58S nanopowders by sol-gel method. Also, effect of aging time on morphology, structure and particle size for biomedical applications was investigated. Bioglass-58S powders were analyzed by X-ray diffraction patterns (XRD), Fourier transform infrared spectroscopy (FTIR), zetasizer instrument, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The XRD results showed the powder is amorphous and glassy. According to FTIR spectroscopy, silicates bonds were formed in all powders. Zetasizer curves proved that the particle sizes of powders and agglomerates were increased by aging time. The SEM images confirmed these results, too. As well, TEM observations showed the increasing of aging time caused the growth of grain sizes between 50-200 nm. Since, these powders synthesized in nanometric scale, the reaction of material and body can accelerate, whereupon improve bone formation process.
