Heats of formation of Ce-Sb alloys

The isothermal section of the Ce–Co–Sb ternary system at 400°C

“…The X-ray diffraction analysis confirmed the existence of the 14 binary compounds in the Ce-Co-Sb ternary system at 400 • C: Ce 24 Co 11 , CeCo 2 , CeCo 3 , Ce 2 Co 7 , Ce 5 Co 19 and Ce 2 Co 17 in the Ce-Co system; CoSb, CoSb 2 and CoSb 3 in the Co-Sb system; Ce 2 Sb, Ce 5 Sb 3 , Ce 4 Sb 3 , CeSb and CeSb 2 in the Ce-Sb system. The binary compounds found in this work are in well agreement with those compounds reported in the literatures for Ce-Co [10], Co-Sb [11] and Ce-Sb [12] binary systems. The structure types and lattice parameters of these com- pounds are listed in Table 1.…”

Isothermal section of the Ce–Au–Sb system at 870K

“…Although, the interactions between the components in the Ce-Au, Au-Sb and Ce-Sb binary systems have been studied in Refs. [1][2][3][4][5][6] and the ternary ZrCuSi 2 -type CeAuSb 2 [7], Y 3 Au 3 Sb 4 -type Ce 3 Au 3 Sb 4 [8], UHg2-type Ce(Au 1−x Sb x ) 2 [9] and CaIn 2 -type CeAuSb compounds were reported earlier [10] (Table 1), no profound investigations of Ce-Au-Sb system were ever made. This work is devoted to the search and identification of new phases, precise structural characterization of compounds and construction of the isothermal section of Ce-Au-Sb system at 870 K within the concentration range 0-50 at.% Ce.…”

Thermodynamic stability studies of Ce-Sb compounds with Fe

“…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]. However, simply comparing the enthalpy of formation cannot support the stability of Ce-Sb compounds.…”
