N2  - A series of 27 oxides of the type Ca3&#8211;xSrxAl2O6, 3 &pound; x &pound; 0, were prepared as polycrystalline powders. The compounds are isostructural with Ca3Al2O6, space group Pa3&#8211;, and their structures were refined from powder neutron and/or X-ray diffraction data by using the Rietveld method. The evolution of Ca/Sr site occupancies, with x, was determined. It was found that the Ca and Sr cations display strong site selectivity, the smaller Ca 2+ cations preferentially occupying the six-coordinate sites. The relationship between the observed structures and the reactivity of Ca3Al2O6 in Portland cement is discussed.
