Abstract
The Bi2O3–SnO2 system was studied by differential thermal analysis, x-ray diffraction, and Knudsen cell mass spectrometric measurements. Bi2Sn2O7 was shown to have an orthorhombic structure with lattice parameters a= 12.262 Å, b = 3.765 Å, and c = 7.957 Å. Mass spectrometry was used to determine the vapor composition over the condensed phase in different phase regions and the partial pressures of the main vapor species. The standard enthalpy of formation of Bi2Sn2O7 was calculated. Based on the experimental data, the T–x and p–T projections of the Bi2O3–SnO2 phase diagram were mapped out.
