摘要：

Mono-dispersed silica particles were prepared with a tube flow reactor. To prevent effects of residence time distribution, nitrogen gas was introduced to separate the reaction fluid into segments. Then, TEOS monomer was added twice along the reaction tube path to increase the growth rate of particles. As a result, silica fine particles of narrow size range can continuously be produced in the tube reactor.
