Phase diagram for the system CuBr–LiBr was determined by differential scanning calorimetry and X-ray powder diffraction. The
system exhibits a significant solid solubility of the components, especially LiBr in the respective polymorphic modifications
of CuBr. Another feature of the system CuBr–LiBr is the occurrence of five invariant three-phase equilibria, which have been
assigned to one eutectic (684 K), one peritectoid (668 K), and three eutectoids (679, 645, and 521 K). From the experimental
results, formation of a compound LiCuBr2, at 521 K is discerned.
