Structure and carbonate orientation of vaterite (CaCO3)

American Mineralogist, 2009
First-principles calculations and molecular-dynamics simulations are employed in this study to further our understanding of the crystal structure and orientational order of carbonate ions in vaterite, which is the least stable polymorph of calcium carbonate.

Growth of vaterite and calcite crystals in gels

Materials Research Bulletin, 1971
Abstract Crystals of vaterite and calcite have been simultaneously grown in sodium metasilicate-acetic acid gels. The crystals were characterized by x-ray diffraction and infrared spectroscopy. The growth ratios of vaterite and calcite are functions of gel pH values.

Vibrational assignments in borates with the vaterite structure

Journal of Molecular Spectroscopy, 1969
Abstract The vibrational spectra of rare-earth borates with the vaterite structure are interpreted on the basis of a planar T -shape for the borate ion. A normal coordinate analysis of this ion is given, using a general valence force field (GVFF). The B 3 O 9 ring with C 3 v symmetry is also considered as a basis for the interpretation of the ...
