Abstract

A starting material composed of calcium carbonate is dissolved in a nitrate aqueous solution containing either Ca(NO.sub.3).sub.2 or NH.sub.4 NO.sub.3 under application of heat and pressure. The starting material is hydrothermally synthesized within the nitrate aqueous solution to effect the rapid growth of calcium carbonate single crystal.
