Differential thermal analysis and X‐ray diffraction of 12 different compositions in the phase diagram KCl–MgO disclose that there exists an area of solid solution, extending from ca. 30–80 equiv. % of MgO/2 (10–55 wf. % MgO), and, depending on the composition, from ca. 759°–775°. Besides the solid solution solid MgO occurs in this area. No chemical reaction between the components takes place.
