New powder X-ray diffraction data of Ca12Al14O32 F2 (C11A7f), a cementitious compound, were collected on a conventional X-ray powder diffractometer: the cubic cell parameter is a = 11.96269(6) Å, volume 1711.93(2) Å3 (space group I-43d). The strongest lines are: 4.887(100), 2.675(95), 2.992(46), 2.442(46), 2.184(37), 3.198(32), 1.599(26), and 1.941(25). Reported intensities are validated by Rietveld analysis. The new data consist of measured intensities and cover a wider 2θ angular range with respect to the calculated PDF 25-394 and the indexed PDF 36-678: experimental, calculated, and difference patterns are reported together with crystal-chemical considerations.

Abstract

New powder X-ray diffraction data of Ca12Al14O32 F2 (C11A7f), a cementitious compound, were collected on a conventional X-ray powder diffractometer: the cubic cell parameter is a = 11.96269(6) Å, volume 1711.93(2) Å3 (space group I-43d). The strongest lines are: 4.887(100), 2.675(95), 2.992(46), 2.442(46), 2.184(37), 3.198(32), 1.599(26), and 1.941(25). Reported intensities are validated by Rietveld analysis. The new data consist of measured intensities and cover a wider 2θ angular range with respect to the calculated PDF 25-394 and the indexed PDF 36-678: experimental, calculated, and difference patterns are reported together with crystal-chemical considerations.
