The paper reports the first attempt at changing cooling treatment of synthesizing method in order to investigate its effect on the physical properties of sol-gel derived nano bioactive glass in the system 58SiO2–33CaO–9P2O5 (wt.%). We hypothesized that the method of cooling may affect the properties of nano bioactive glass. To test this hypothesis, two different method of cooling treatment was applied after calcinations in synthesizing method. The obtained nano glass was analyzed for its composition, crystalinity and morphology through X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and surface electron micrograph (SEM). The SEM images showed that the morphology of nano bioactive glasses were completely changed. Other properties of these two morphologically different nano bioactive glasses were strongly discussed.
