Abstract
In the present work, silica extracted from the agricultural waste material; rice husk (RH) was utilized for the synthesis of biocompatible glass of general composition SiO2-P2O5-CaO-MgO-MoO3. In the synthesized glasses P2O5 (5%) and CaO (25%) was kept constant whereas MgO and MoO3 was varied from 10% to 20% and 0% to 5% respectively. The structural, morphological, elemental and functional properties of silica as well as the derived glasses were analyzed by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray spectroscopy (EDX) and Fourier Transform Infrared (FTIR) spectroscopy techniques. The effect of MoO3 on the structural and thermal properties of silicate phosphate glasses has been studied in details. The bioactivity of as-synthesized glass samples were further evaluated after immersion in Simulated Body Fluid (SBF) solution which shows bioactive properties thus enabling them to be used as scaffolds in implant materials.
