The Preparation of Bioactive Glass Microspheres in W/O Emulsion

Abstract:

The emulsion combining sol-gel method was used to prepare spherical bioactive glass in the present work. This method involves a two-stage synthesis process: the pre-hydrolysis of tetraethyl orthosilicate (TEOS) in an aqueous acidic solution using templates, and afterward the fabrication of silica spheres by pH induced rapid gelation in a W/O emulsion. Through controlling the two stages separately, the particle size and morphology of silica spheres can be adjusted. These results indicated that emulsion method could supply a good way to prepare glass microspheres.
