| Abstract: | The solid solubility of the SrAl2O4-CaAl2O4 system has been investigated using high resolution synchrotron powder diffraction methods. Analysis of the patterns shows there is a limited composition range at which single phase samples can be obtained, x<0.25 and x>0.75 for the series Ca1−xSrxAl2O4. At intermediate compositions up to three phases are observed, two monoclinic and one hexagonal. The temperature dependence of the structures is also described. |
