The synthesis of silica particles using three dimensional microreactor

Abstract

In this study a three dimensional microreactor was used for the synthesis of the silica particles. By using the microreactor the silica particles could be prepared from the water glass-sol by the sol-gel process and thermal treatment. The obtained silica particle size was 54-86μm which greatly depends on the inside diameter and flow velocity of inner flow, so it is easy to be controlled by these parameters.
