Notes:
Abstract Preparation of spherical hydrous silica oxide particles via sol-gel processing was rarely reported. In this study, spherical silica particles were obtained in TEOS/AcOEt/AcOH 50% aq. system. The combination of AcOEt and AcOH 50% aq. widened the spherical particle-forming region. Their size ranged from some ten micrometers to some hundreds micrometers. Hydrophilic molecules or powders like Rhodamine 6G and phosphorescent powders were encapsulated in the spherical particles.
