• mixed alkali-zinc diphosphates
• solid solutions

Phase relationships in the LiNaZnP2O7-LiKZnP2O7 system have been studied. For the first time a vast region of solid solutions of the rhombic syngony LiNa1 - x K (x) ZnP2O7 containing simultaneously three alkali cations was found. The miscibility is broken at the temperature of the polymorphous transformations LiKZnP2O7 (270 degrees C) and below, with the formation of the two-phase region of the solid solution with the rhombic and monoclinic structures (0.85 %26lt;= x %26lt;= 1 at 25 degrees C).
