Abstract—A quaternary reciprocal system of fluorides, chlorides, and bromides of lithium and potassium was
partitioned into simplexes by a geometric method and by a graph method. Phase transformations and chemical
reactions in the boundary ternary reciprocal systems were described. A conversion line was experimentally
studied, and information on crystallizing phases within the composition prism of the Li,K||F,Cl,Br system was
obtained and confirmed by X-ray powder diffraction data. An immiscibility region in the LiF–KCl–KBr stable
triangle was outlined.
