For the first time specific heats of the face centered cubic solid solutions (Bi 2 O 3 ) 1− x (Y 2 O 3 ) x in the temperature range 350–1000 K were measured by means of Differential Scanning Calorimetry. Samples were also investigated with thermal expansion. The results showed the phase transitions for (Bi 2 O 3 ) 0.75 (Y 2 O 3 ) 0.25 , which is acsribed to δ → δ* change in lattice mentioned in literature and for (Bi 2 O 3 ) 0.58 (Y 2 O 3 ) 0.42 , which is connected with a metastable behaviour of this sample.
