Mv. Gorev et al., EFFECT OF SC SUBSTITUTION AND PRESSURE ON PHASE-TRANSITION IN RB2KGAF6 ELPASOLITE, Ferroelectrics. Letters section, 22(5-6), 1997, pp. 127-133
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.
