Аннотация
Phase equilibria were experimentally studied in the system LiF–KI–KF–K2CrO4, which is the stable tetrahedron of the quaternary reciprocal system Li, K∥F, I, CrO4. Differential thermal analysis revealed the compositions and transformation temperatures at the eutectic point E□ 488 (L ⇄ LiF + KF + KI + α-K2CrO4) and the peritectic point P□ 510 (L + K3FCrO4 ⇄ KI + α-K2CrO4 + KF). A computer model of the phase complex of the system was built, which can predict phase transformations at an arbitrary composition in the system. Isothermal sections of the systems were constructed, using which the phase composition at the temperature of the section can be calculated.
