Specific heats of FCC solid solutions of the Bi2O3-Y2O3 system

For the first time specific heats of the face centered cubic solid solutions (Bi2O3)1−x(Y2O3)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 (Bi2O3)0...

Zusammenfassung:For the first time specific heats of the face centered cubic solid solutions (Bi2O3)1−x(Y2O3)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 (Bi2O3)0.75 (Y2O3)0.25, which is acsribed to δ → δ* change in lattice mentioned in literature and for (Bi2O3)0.58(Y2O3)0.42, which is connected with a metastable behaviour of this sample.
