Thermodynamic Assessments of the Bi-Tb and Bi-Y Systems

Abstract

By using the calculation of phase diagrams (CALPHAD) method, the thermodynamic assessments of the Bi-Tb and Bi-Y systems were carried out based on the available experimental data including thermodynamic properties and phase equilibria. Gibbs free energies of the liquid, hcp, bcc, and rhombohedral phases in the Bi-Tb and Bi-Y systems were modeled by the substitutional solution model, and the intermetallic compounds (phases) in these two binary systems were described by the sublattice model. An agreement between the present calculated results and experimental data was obtained.

Standard partial molar volumes and viscosity B-coefficients of ionic liquids [Cnmim]Br (n=4, 6, 8) in alcohols at 298.15K

“…Our experimental results indicate that the strength of the interactions between the ILs and alcohol increases in the order: methanol N 1-propanol N 1-pentanol. This is in agreement with the results reported in literature [34].…”

Current vs. voltage behavior of Hebb-Wagner ion-blocking cell through compound (Bi1.46Y0.54O3) decomposition and decomposition kinetics

“…It was further expected that those three phases would likely be YDB, Bi and Bi 2 O 3 for U ⁎ is equal to that of pure Bi 2 O 3 [8]; the more noble metal normally tends to be reduced first when a homovalent binary oxide solution is reduced [13]; Y 2 O 3 is much more stable than Bi 2 O 3 [15], and mutual solubilities of Bi and Y are negligible [16]. It has been found to be true indeed.…”

Thermodynamic Study of Sn-Bi-Nd, Tb Ternary Systems

“…In the Sn-Bi-Tb ternary system, the thermodynamic assessments of the Sn-Bi, Bi-Tb and Sn-Tb binary systems were carried out by Lee et al [6], Wang et al [8] and Wang et al [10] respectively. On the basis of the assessed thermodynamic parameters of relevant binary systems [6,8,10], the phase equilibrium of the Sn-Bi-Tb ternary system has been calculated.…”

“…On the basis of the assessed thermodynamic parameters of relevant binary systems [6,8,10], the phase equilibrium of the Sn-Bi-Tb ternary system has been calculated. Figures 4-6 show the calculated isothermal section at 150 °C and 200 °C and longitudinal section.…”
