A preparation method for micron scale spherical silica particles was investigated by combining the hydrosis and condensation of tetraethylorthosilicate (TEOS) in W/O emulsion. The aggregation took place when ammonia was used as catalyst. On the other hand, micron scale spherical silica particles could be obtained in the presence of water instead of ammonia.
