Calcium Carbonate Crystal Forms Formed from Sea Water by Inorganic Processes

Abstract

This study was made to solve the f이lowing questions: (1) Which of the three crystal forms of caJcium carbonate (caJcite, aragonite and vaterite) is produced most predominantly from sea water by inorganic processes. (2) Which of the chemical constituents of sea water has the greatest influence on the polymorphic formation of calcium carbonate? The experimental resuIts show that aragonite alone is favored in sea water media because of the strong influence of magnesium in the water on the crystal formation of caJcium carbonate.
