“…Hybrid materials incorporating functional organic molecules can also be produced by sol-gel routes [9]. The reactivity of the glasses depends on both their porosity and the number of non-bridging oxygens (NBO) that can be controlled by the addition of cations such as Na + , K + , and Mg 2+ which induce a breakdown of the glass network [10,11].…”

Bioactive glass (BG) particles with nominal composition 60SiO 2 -36CaO-4P 2 O 5 (mol%) were prepared by the sol-gel emulsion method. The thermal parameters, morphology, and phase composition were characterized by means of thermal analysis, scanning electron microscopy, X-ray diffraction, and FT-IR absorption spectroscopy. The in vitro bioactivity of the samples was determined by immersing the samples in simulated body fluid. The findings indicated that the sol-gel emulsion method may be useful to prepare BG samples free of crystallization.
