T. Ogihara et al., CONTINUOUS SYNTHESIS OF MONODISPERSED SIL ICA PARTICLES USING COUETTE-TAYLOR VORTEX FLOW, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 103(2), 1995, pp. 151-154
A novel continuous reactor was developed for industrial production of
monodispersed powders via alkoxide route, Couette-Taylor vortex flow w
as used for solution mixing. Each of Taylor vortices can be worked as
a batch reaction vessel, Monodispersed silica powders were prepared by
the hydrolysis of ethyl silicate with water and ammonia in ethanol us
ing this reactor, The results were comparable to those obtained using
batch process, The effect of Taylor number and residence time on the p
article size, particle size distribution, yield, and particle number d
ensity of monodispersed silica powders was investigated, Monodispersed
silica powders could be continuously produced for 5h using this react
or.
