Transport control during the formation of particles of calcium carbonate

• : Micrometer-sized particles of calcium carbonate were formed by adding NaHCO3 (aq) to a buffered aqueous solution of CaCl2 (aq) and polyelectrolytes. Particle morphology and crystal polymorphology were tuned by varying the stirring rate. Vigorous stirring led to the formation of micrometer-sized spherical particles of nanocrystalline vaterite; slow stirring formed rhombohedral nanostructured particles of calcite.
