Aggregates of calcium carbonate microcrystals precipitated from a highly supersaturated aqueous solution were found to form in two stages. At the first stage, high-porosity disordered aggregates (floccules), and at the second, low-porosity ordered ag

A mathematical kinetic model is developed for sorption of radionuclides, occurring via transition of the sorbate atoms initially to the subsurface layer of the particles of a polydisperse sorbent with a known particle size distribution function ϕ(R)

A comparative study of sorption of 90Sr2+ and 90Y3+ cations from aqueous solutions saturated with respect to calcium carbonate on the metastable CaCO3 modifications (aragonite and vaterite) and also on the stable CaCO3 modification (calcite) was carr

The features of migration of positrons in the bulk of vaterite (metastable modification of CaCO3) were studied using positron annihilation lifetime spectroscopy (PALS). Comparison of the lifetime of ortho-positronium determined from the PALS data, wh

The vaterite-to-calcite phase transition in spheroidal vaterite particles produced by reacting aqueous Ca(NO3)2 and Na2CO3 solutions at 20 ± 1°C under 2.6-MHz sonication was studied by scanning electron microscopy and x-ray diffraction. The results

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
