Figure 4
Rietveld analysis. Simulated curve (red solid line) and experimental pattern (small black points) measured on a mixture of NaCl (squares above reflections, mass ratio 58.5 ± 0.3%, refined ratio 60.0 ± 0.2%) and sodalite (circles above reflections, mass ratio 41.4 ± 0.3%, refined ratio 39.9 ± 0.2%), with the difference plot [F^{\,2}_{\rm obs} - F^{\,2}_{\rm calc}] shown at the bottom (black solid line). The fitted red line was calculated using the fundamental parameters approach. Seven scans were measured on the same sample holder (Rp = 4.2%). The input file is provided in the supporting information.
