Stable Prenucleation Calcium Carbonate Clusters

Gebauer, Denis, Völkel, Antje, Cölfen, Helmut·2008·Science

Abstract

Calcium carbonate forms scales, geological deposits, biominerals, and ocean sediments. Huge amounts of carbon dioxide are retained as carbonate ions, and calcium ions represent a major contribution to water hardness. Despite its relevance, little is known about the precipitation mechanism of calcium carbonate, and specified complex crystal structures challenge the classical view on nucleation considering the formation of metastable ion clusters. We demonstrate that dissolved calcium carbonate in fact contains stable prenucleation ion clusters forming even in undersaturated solution. The cluster formation can be characterized by means of equilibrium thermodynamics, applying a multiple-binding model, which allows for structural preformation. Stable clusters are the relevant species in calcium carbonate nucleation. Such mechanisms may also be important for the crystallization of other minerals.

  • A variety of precursor phases exist in the early stages of carbonate crystallization, including prenucleation clusters, metastable liquid-like precursors, mesocrystals and amorphous and nanophase precursors.

    “Recent studies have shown that a variety of precursor phases exist in the early stages of carbonate crystallization, including prenucleation clusters, metastable liquid-like precursors, mesocrystals and amorphous and nanophase precursors [114-123].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
