Abstract
New powder X-ray diffraction data ofCa12Al14O32F2(C11A7f), a cementitious compound, were collected on a conventional X-ray powder diffractometer; the cubic cell parameter isa=11.96269(6) Å, volume 1711.93(2) Å3(space groupI-43d(No. 220)). The strongest lines are 4.887(100), 2.676(95), 2.992(46), 2.443(46), 2.185(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.
