Se-Sn (Selenium-Tin) R.C. Sharma and Y.A. Chang The assessed Sn-Se phase diagram is based primarily on the work of [06Pel], [ 09Pel], [64Vas], [66Kha], [68Gas], [71Mel], and [82Ale]. The liquid miscibility gap in the (Sn)-SnSe region and the Se-rich portion of the liquidus have not been determined experimentally and are thus shown as dashed lines in the assessed diagram. Two eutectics, L1 = (Sn) + SnSe and L2 = SnSe2 + (Se), are very close to pure Sn and pure Se, respectively, and have not been determined experimentally. In the assessed diagram, the eutectic temperatures for these reactions are arbitrarily shown at ~1 C below the melting points of pure Sn and pure Se, respectively. The monotectic, L2 = L1 + SnSe, in the (Sn)-SnSe region and the eutectic, L2 = SnSe + SnSe2, between SnSe and SnSe2 have been determined by [ 66Kha] and [82Ale]. The mutual solid solubilities of Sn and Se are very limited. [38Jen] reported the solubility of Se in (Sn) to be 0.05 at.% Se at 200 C. There are no reported measurements of the solubility of Sn in (Se). 06Pel: H. Pelabon and H. Moissan, Compt. Rend., 142, 1147-1149 (1906) in French. 09Pel: H. Pelabon, Ann. Chim.
