抜粋

Effects of O 2- or OH - ion incorporation on the cage geometry in 12CaO·7Al 2O 3 (C12A7) crystals are examined by the maximum entropy method (MEM)/Rietveld analyses of synchrotron powder X-ray diffraction data. Presence of an extraframework anion in a cage causes inward displacements of two Ca 2+ ions axially coordinating to the anion. The OHion locates at the cage center and induces smaller symmetric displacements of the two Ca 2+ ions, while the O 2- ion likely locates on off-axis positions and induces larger asymmetric Ca 2+ ion displacements.
