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

The ternary system Bi–Fe–Sb has been investigated using differential thermal analysis (DTA), differential scanning calorimetry (DSC) and electron probe microanalysis (EPMA). Two isoplethic sections were studied: 80 at.% Bi and 30 at.% Sb. An isothermal section of the phase diagram was also studied at 523.15 K. Three invariant reactions were found: two ternary transitory peritectics and one ternary monotectic. No ternary compounds were found. In addition, a thermodynamic assessment was conducted.
