Calcium carbonate has been synthesized from Ca(OH)_2 in ethanol-ethylene glycol solvent by carbonation and aging process. Carbonation in organic solvent caused Ca(OH)_2 to form a white gelatinous CaCO_3 product, which was then destroyed by aging process. The calcium carbonate precipitated and agglomerated in these steps was composed of stable calcite, and meta-stable aragonite and vaterite. These meta-stable particles were shaped either peanut-like or sphere. When a little amount of distilled water was added to organic solvent, the meta-stable phases remarkably decreased, whereas stable calcite increased. When Ca(OH)_2 was carbonated with water addition increased to 2vol% of the total organic solvent and aged at 40℃, only rhombic calcite was synthesized.
