“…However, available data are very limited. Current knowledge is still constrained to the binary systems, including the Ce-Sb [10] and Fe-Sb [11] systems. There are four known intermetallic compounds (Ce2Sb, Ce4Sb3, CeSb and CeSb2) in the Ce-Sb system [10], and one intermediate compound Fe1.27Sb and one intermetallic compound FeSb2 in the Fe-Sb system [11].…”

Based on the enthalpy of formation, there is a greater driving force to form Ce-Sb compounds compared to Fe-Sb compounds [12] [13].…”

Lanthanide fission products can migrate to the fuel periphery and react with cladding, causing fuelcladding chemical interaction (FCCI). Adding a fuel additive dopant, such as Sb, can bind lanthanide, such as Ce, into metallic compounds and thus prevent migration. The present study focuses on the thermodynamic stability of Ce-Sb compounds when in contact with the major cladding constituent Fe by conducting diffusion couple tests. Ce-Sb compounds have shown high thermodynamic stability as they did not react with Fe. When Fe-Sb compounds contacted with Ce, Sb was separated out of Fe-Sb compounds and formed the more stable Ce-Sb compounds.

Heusler alloys have been considered as one of the most promising thermoelectric materials for electrical power generation in a temperature range of 500–800 °C. Establishment of phase diagrams allows one to predict formation, equilibria, and stability of phases in of these ternary alloys. In this work we report on the simulation and investigation of phase diagram and phase equilibria in ternary Ti-Fe-Sb system which is of considerable interest for thermoelectric applications. The simulation was carried out using the CALPHAD method in Pandat software. The existence of the thermoelectric Heusler TiFe1.5Sb phase was revealed in a temperature range from 970 to 1070 K. The equilibria between TiFe1.5Sb and other phases were determined. The entropy of formation was calculated for the phases existing at 970, 1020 and 1070 K using a fitting approach. A narrow equilibrium region containing pure body centered cubic Fe and TiFe1.5Sb was found.

“…In the studies of Pei et al 20) and Boa et al, 21) FeSb was described by a two-sublattice model Fe(Fe,Sb). In the studies of Zhang 6) and Li et al, 22) FeSb was treated by a threesublattice model (Fe,Va) 1/3 (Fe,Va) 1/3 (Sb) 1/3 (the symbol "Va" represents a vacancy in this work). It is reasonable to adopt the three-sublattice model in this study because FeSb has a hexagonal structure of the NiAs prototype, 2325) and this kind of three-sublattice model is used to describe the CoSb compound in the thermodynamic assessment of the CoSb binary system.…”
