TEM and Atom Probe Investigation of Calcium Carbonate Precipitation in Seawater

“…SEM analysis of the resulting precipitations shows an evolution of carbonate growth morphology that does not follow the Terrace Ledge Kink model for crystal growth [3]. Previous work shows that there appears to be an amorphous calcium carbonate (ACC) surface layer nm's thick above the overgrowth; and that the overgrowth itself seems to be growing epitaxially to the substrate [4].…”
