Fe-Sb (Iron-Antimony) H. Okamoto The assessed phase diagram for the Fe-Sb system is based mainly on the experimental work of [08Kur], [34Vog], [35Fou], [39Gel], [61Vec], [69Kje], [ 72Mai], [74Nag], and [79Ko], with review of the data of [43Age], [67Hil], [ 71Pre], and [75Dyn] and on thermodynamic considerations. The equilibrium phases are (1) the liquid, L; (2) the fcc terminal solid solution, (gFe); (3) the bcc terminal solid solution, (aFe); (4) hexagonal NiAs-type e; (5) orthorhombic FeSb2; and (6) the aAs-type terminal solid solution, (aSb). The solubility of Sb in (gFe) at 1150 C is 0.93 [34Vog, 38Sve] or 1.1 at.% Sb [67Hil]. The (aFe) solidus is not well defined. The assessed boundary was drawn by assuming 5 at.% solubility of Sb in (aFe) at the eutectic temperature. The initial slope of the solidus at 0 at.% Sb is about - 48 C/at.% Sb, which is calculated from the liquidus slope using the van't Hoff relationship with 13 800 J/mol [83Cha] for the enthalpy of fusion of bcc Fe. The initial slope of the (aSb) liquidus is about -3.4 C/at.% according to the van't Hoff relationship assuming 19 900 J/mol [83Cha] for the enthalpy of fusion of Sb and no solubility of Fe in (aSb). Another phase, "FeSb3" (not superconducting down to 1.45 K), was reported only by [48Ale]. aPo-type, simple cubic FeSb4 exists as a transient phase during the transformation from a rapid-quenched amorphous phase to the equilibrium state [ 72Chy]. The Curie temperature (TC) of pure aFe is 770 C [82Swa]. [11Por] and [35Fou] found that Sb has little effect on TC of (aFe). TC of (aFe) + e two-phase alloys is 765 C [72Mai], whereas that of e is 220 C [72Mai]. [70Hol] observed no evidence of magnetic ordering in FeSb2 at 4.2 K. [72Mai] found that annealed FeSb2 is ferromagnetic, with TC = 565 C, whereas quenched FeSb2 is paramagnetic. 08Kur: N.S. Kurnakow and N.S. Konstantinow, Z. Anorg. Allg.
