STRUCTURAL AND MORPHOLOGICAL PROPERTIES OF SOL-GEL DERIVED BIOGLASSES PREPARED UNDER VARIOUS CONDITIONS. Authors: G. MELINTE, L. BAIA, S. SIMON. |
||||||
Abstract: Bioactive glasses belonging to the 60SiO2-36CaO-4P2O5 (mol %) system have been prepared by sol-gel method under various conditions, using different molar ratios of HCl:TEOS and replacing H2O with H2O2. The obtained bioglasses were characterized by X-ray powder diffraction, BET analysis and Raman spectroscopy. Depending on synthesis conditions, crystalline Ca2SiO4 or hydroxyapatite phases are developed in some samples. At the same time, the preparation conditions influence the specific surface area and the connectivity of silica units in the structural network of these samples.
Keywords: bioactive glasses; sol-gel; XRD; BET; Raman spectroscopy. |
