Ga-Sb (Gallium-Antimony) T.L. Ngai, R.C. Sharma, and Y.A. Chang The assessed phase diagram for the Ga-Sb system is based on thermodynamic modeling and calculations, with review of the data of [55Gre], [55Kos], [58Gla] , [63Hal], [68Mag], [77Che], and [78Ded]. The system is characterized by a congruently melting intermediate phase, aGaSb, that exists at 50 at.% Sb and two eutectic reactions, one each in the Ga-aGaSb and aGaSb-Sb regions of the phase diagram. The mutual solid solubilities of Ga and Sb are negligible and have not been experimentally determined. [62Min], [63Jam], [63Jay2], and [78Liu] reported that at high pressures aGaSb transforms to a different polymorph, bGaSb. The transition pressure at room temperature was determined to be between 60 and 90 kbar. [63Jay1] determined the melting temperatures of aGaSb and bGaSb as a function of pressure. The L- aGaSb-bGaSb triple point is at 385 C and 56.5 kbar [63Jay1]. 55Gre: I.G. Greenfield and R.L. Smith, Trans AIME, 203, 351-353 (1955). 55Kos: W. K”ster and B. Thoma, Z.
