Synthesis of calcium carbonate in trace water environments

Calcium carbonate (CaCO₃) was synthesized from diverse water-free alcohol solutions, resulting in the formation of vaterite and calcite precipitates, or stable particle suspensions, with the dimensions and morphologies depending upon the conditions used. The obtained results shed light on the importance of solvation during crystallization of CaCO₃ and open a novel synthetic route for its precipitation in organic solvents.
