Stacking sequence variations in vaterite resolved by precession electron diffraction tomography using a unified superspace model

Popis výsledku v původním jazyce

As a metastable phase, vaterite is involved in the first step of crystallization of several carbonate-forming systems including the two stable polymorphs calcite and aragonite. Its complete structural determination would shed important light to understand scaling formation and biomineralization processes. While vaterite’s hexagonal substructure and the organization of the carbonate groups within a single layer is known, conflicting interpretations regarding the stacking sequence remain and preclude the complete understanding of the structure. To resolve the ambiguities, we performed precession electron diffraction tomography to collect single crystal data from 100 K to the ambient temperature. The model was refined against PEDT data using the dynamical refinement procedure including modulation and twinning as well as against x-ray powder data by the Rietveld refinement.n
