Abstract

Colloidal spherical particles of SiO2, Al(OH)3, and BaTiO3 of narrow size distributions were produced in a continuous static mixer tubular reactor system. Several experimental parameters, including the flow rate, reaction temperature and time, reactant concentrations, and the dimensions of the reactor, were varied in order to establish the optimum conditions required for each material. The results were compared with those obtained in batch systems. Monodispersed colloids can be generated at a rate as high as 50 pounds per day using the described laboratory scale continuous reactor.
