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 supensions, with dimension and morphology depending upon the condition used. The obtained results shed light on the importance of water molecules during crystallization of CaCO3 and open a novel synthetic route for its precipitation in organic solvents.
