Precipitation is a promising process for nanoparticle production because it is a fast, economic process and simple to design. In the present work, barium sulfate particles were produced by discontinuous precipitation in a stirred tank reactor. Particle sizes of less than 100 nm were achieved. Particle size distributions strongly depend on the mechanical mixing and the molar ratio of the reactants as well as on the stabilization of the particles in the suspension.
Die Fällung ist ein vielversprechender Prozess zur Nanopartikelherstellung, da er schnell, kostengünstig und verfahrenstechnisch einfach zu gestalten ist. Im Rahmen der vorliegenden Untersuchungen wurden Bariumsulfatpartikel in diskontinuierlichen Fällungsversu-chen in einem Rührkesselreaktor hergestellt. Es wurden Partikelgrößen unter 100 nm erreicht. Die Partikelgrößenverteilungen hängen stark von der Vermischung und dem stöchiometrischen Verhältnis der Reaktanden sowie von der Stabilisierung der Partikeloberfläche ab.
