Notes:
Abstract Calcium carbonate was precipitated by mixing aqueous solutions of sodium carbonate and calcium nitrate in the presence of water-soluble polymers. When the former was poured into the latter, in which a certain amount of sodium poly(styrenesulfonate) was dissolved, monodisperse spherical crystals were created. The crystal form was vaterite, although, in the absence of the polymer, calcite crystals were obtained in rhombic shape. The factors deciding the shape and form of the crystal were investigated and the role of polymer in the formation of unique crystals was discussed.
