Nano Bioactive Glass based on the CaO–P2O5–SiO2 System; synthesized by sol–gel method

The synthesis of SiO2-CaO -P2O5 bioactive glass was carried out by the sol-gel method At considerably lower temperatures than required for conventional melting methods. Sol-gel derived bioglass material was crushed into powder and its biocompatibility evaluation was assessed through immersion studies in simulated body fluid (SBF) for different time intervals to examine the formation of a hydroxyapatite layer in SBF. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis studies were conducted before and after contact of the material with SBF to characterize the chemical and physical properties of the sol-gel derived bioactive powders.
