Abstract
Solid solutions Rb2KGaxSc1-xF6 (x = 1.0; 0.95; 0.9; 0.8; 0.6) were stu died by X-ray, neutron, calorimetric and DTA under hydrostatic pressur e methods. Both heat capacity and entropy are strongly influenced by x concentration. According to (T vs. x) phase diagram suggested the pha se transition temperatures of compounds with x from 1.0 to 0.8 belong to the same phase boundary.
