The crystallography of CA 1−xF x using X-ray powder diffraction techniques

Abstract

The system CA-CF shows two solid solutions series: C(A,F) and C(F,A). We have analysed the variation of the cell parameters of the solid solution CA 1−xF x (x indicating molar fraction of CF) depending on the initial weight percent of CF, using X-ray diffraction (XRD) and two different methods of cell parameter refinement: Peak Maxima-Matching Method and Rietveld Profile-Fitting Method. The solid solution end is placed at 16'5 wt% of CF (x=0.125). This value has been calculated through the aluminium population factor in the CA phase structure, as well.
