Formation of CaCO3 Deposits on Hard Surfaces-Effect of Bulk Solution Conditions and Surface Properties
(2013) In ACS Applied Materials and Interfaces 5(10). p.4035-4045- Abstract
- We have studied nucleation and crystal growth of calcium carbonate on hard surfaces, i.e. stainless steel and silica, at different temperatures, in relation to the corresponding bulk processes, using scanning electron microscopy (SEM), X-ray diffraction (XRD), and ellipsometry. In the bulk solution, a mixture of all three calcium carbonate crystalline polymorphs, calcite, aragonite, and vaterite, as well as amorphous particles was observed at 25 degrees C, while at 55 degrees C aragonite and calcite crystals dominated. On surfaces only calcite crystals were observed at 25 degrees C, whereas aragonite and calcite crystal adsorbed on the surfaces at 55 degrees C. Two kinds of nucleation and adsorption mechanism of CaCO3 crystals on hard... (More)

On surfaces only calcite crystals were observed at 25 degrees C, whereas aragonite and calcite crystal adsorbed on the surfaces at 55 degrees C. Two kinds of nucleation and adsorption mechanism of CaCO3 crystals on hard surfaces were observed, depending on the surface orientation (vertical or horizontal, i.e., subject to sedimentation) in the bulk solution. A model for the relation between interfacial layer structure, the substrate, and the solution crystallization is discussed based on the observed difference in deposition between type of surfaces and surface orientation. In addition, the effect of magnesium ion on the morphology of calcium carbonate crystals is discussed. (Less)
