X-ray Diffraction Data on Two High-Pressure Phases of Calcium Carbonate
Abstract
X-ray diffraction studies conducted at high pressure with a beryllium pressure vessel show that compression parallel to the c-axis of CaCO(3)-I (calcite), as the phase boundary of CaCO-(3)II (modified calcite type) is approached, results in a relative reduction of the c-axis of phase II of several times that of the a-axes. Such data are not consistent with previously proposed anion disorder in CaCO(3)-II. At 18.7 +/- .5 kb and room temperature a new phase of CaCO3 has been observed that is assumed to be phase III found by Bridgman. At this pressure the x-ray diffraction pattern can be indexed as orthorhombic KNO3-IV type, with a0 = 8.90 +/- .01 A, b0 = 8.42 +/- .01 A, and c0 = 7.14 +/- .01 A (Z = 10).

“Several models were proposed based on powder-like data (Davis, 1964;Hagiya et al., 2005), but any attempt to correctly index the diffraction pattern failed.”

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.
