Abstract
Phase relations in the Bi2O3–SnO2 system have been studied using differential thermal analysis, differential scanning calorimetry, X-ray diffraction, and the sessile drop method. The C p (T) curve obtained in the range 350–960 K has a number of extrema, which are attributable to structural changes in Bi2Sn2O7. The experimental C p data have been used to evaluate the thermodynamic properties of the oxide compound.
