The ternary bismuth–iron–antimony system: Experimental phase diagram study and thermodynamic evaluation

Thermodynamic assessment of the Co–Fe–Sb system

“…Recently, the phase equilibria in the Fe-Sb binary system were studied by Sun and Zeng [38] using X-ray powder diffraction with the aid of DTA and optical microscope and by Boa [16] using DTA, differential scanning calorimetry (DSC) and electron probe microanalysis (EPMA).…”

“…The Fe-Sb binary system was firstly assessed by Pei et al [15] and recently by Boa et al [16]. Compared with the assessments of Refs.…”

“…Compared with the assessments of Refs. [15,16], the necessity of the re-assessment of the Fe-Sb binary system is in view of the following points: (1) The three-sublattice model Table 1 The list of the symbols used in the Co-Fe-Sb ternary system a .…”

“…Based on the literature reported Co-Fe, Co-Sb and Fe-Sb systems [12][13][14][15][16], the thermodynamic description of the CoFe-Sb ternary system is optimized together with the re-assessment of the Fe-Sb system, in which the obtained experimental heat capacities of both the non-stoichiometric compound β(FeSb) and the stoichiometric compound ζ 2 FeSb 2 [17,18] are paid special attention, and the activities of iron and antimony at 1423 K [19] are further considered.…”

A Thermodynamic Modeling of the Fe–Nd–Sb System

“…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).…”
