Investigation of the precipitation of barium sulfate nanoparticles

Abstract

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. © 2008 Wiley-VCH Verlag GmbH & Co.
