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 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%).
