Title: Structure and morphology of electrodeposited CaCO{sub 3}: X-ray diffraction and microscopy studies

Abstract

A good understanding of the nucleation and growth of calcium carbonate phases is of considerable importance in a wide variety of applications, such as the control of scaling in cooling water systems, corrosion inhibition in marine systems, and geological mineralization and cementation processes. The structure and morphology of electrochemically deposited calcium carbonate have been investigated as a function of temperature, magnesium ion concentration, organic inhibitors, and deposition potential. At 25 C, microcrystals of calcite grew with their [104] planes parallel to the electrode surface. In the presence of magnesium chloride, a mixed phase of calcite and magnesium calcite, as well as aragonite, was formed. Organic inhibitors varied in their effectiveness in inhibiting calcite formation, e.g., 2-phosphonobutane, 1,2,4-tricarboxylic acid (PBTC) performed better than ethanediphosphonic acid (EDPA).
