The compounds formed by the hydration of single-phase samples of the mixed, solid solution, Ca/Sr aluminates, Ca3-xSrxAl2O6, 3≤x≤0 have been studied using high-resolution synchrotron powder diffraction. Hydration of these mixed metal aluminates generally resulted in the formation of at least two hydrogarnet phases, one Ca-rich and the other Sr-rich. The structures of these hydrogarnets have been refined from neutron or synchrotron powder X-ray diffraction (XRD) data. A simple solubility model to explain the phase separation is presented. © 2002 Elsevier Science Ltd. All rights reserved.
