The iron–antimony system: enthalpies of formation of the FeSb2 and ε-FeSb phases

Supplementary measurements of the primary crystalline phases of the Co–Ni–Sb and the Co–Fe–Sb ternary systems

“…The sealed materials were molten by high frequency induction and shaken to ensure homogenization. The same method was used to prepare the Co-Fe-Sb ternary and the Fe-Sb binary samples in literatures [20][21][22][23]. Finally, the samples, keeping the sealed state, were cooled slowly in furnace to obtain the primary crystalline phases.…”

Thermodynamic Properties of Solid Binary Antimonides

Thermodynamic assessment of the Co–Fe–Sb system

“…Predel and Vogelbein [58] and Boa et al [59,60] measured the enthalpies of formation of β(FeSb) phase at 1060 K and the enthalpies of liquid, ζ 2 FeSb 2 and β(FeSb) phases at 1065 K, respectively. The heat capacities of the compound β(FeSb) in the temperature range from 300 to 1100 K were determined by Perring et al [17] using DSC analyses and those of the compound ζ 2 FeSb 2 from 5 to 1021.2 K were determined by Grønvold [18] using adiabatic-shield calormetry.…”
