Abstract

Primary nanoparticles of vaterite (a metastable form of calcium carbonate) precipitated in aqueous solutions under 2.64-MHz sonication are found to experience layered agglomeration. The vaterite particles are characterized by electron microscopy and x-ray diffraction. The particle size distribution of the precipitate is determined. A mathematical model for layered agglomeration is proposed, and the conclusion is made that, under the experimental conditions used, heterogeneous nucleation of primary vaterite particles takes place.
