Nucleation and Growth Kinetics for the Nanoparticle Precipitation of Barium Sulfate in Microemulsions

Microemulsions Bjoern Niemann, Jan Recksiedler, Dendy Adityawarman, and Kai Sundmacher The formation of nanoparticles in microemulsion droplets is a promising technology for the control of the particle properties, e.g. the particle size distribution or particle shape [1]. Results from barium sulfate precipitation experiments in a semi-batch rushton tank reactor [2] confirmed that the particle size distribution can be controlled by the variation of the initial reactant concentrations inside the droplets. A population balance model was used to analyze this behavior paying particular attention to the nucleation and growth kinetics.
