Study of the ternary system germanium–antimony–tin: experimental phase diagram

The 260°C phase equilibria of the Sn–Sb–Ag ternary system and interfacial reactions at the Sn–Sb/Ag joints

“…The existence of a number of stoichiometric phases such as SbSn, Sb 13 Sn 12 , Sb 3 Sn 2 [10], Sb 3 Sn 4 and Sb 4 Sn 3 [5] have been suggested. Though the existence of Sb 2 Sn 3 stoichiometric compound has not yet been proven by any structural characterization [9,10], the version of two intermetallic compounds SbSn and Sb 2 Sn 3 in the phase diagram, proposed by Predel and Schwermann [9], has been adopted by a lot of literature [13][14][15] and by this study. According to Predel and Schwermann [9], at 260 • C, the Sb phase has a Sn solubility of approximately 12.6 at.%, and the Sn liquid phase has a Sb solubility of approximately 9 at.%.…”

New Insights into Phase Equilibria of the Sb-Sn System

“…[11] Since 1891, many authors have investigated the Sb-Sn alloy system and its phase diagram, resulting in at least twenty assessments. [17][18][19][20][21][22] Controversial versions of the Sb-Sn phase diagram have been proposed [23][24][25][26][27][28] and the most widely accepted was reported in the Massalski compilation, [29] which was based mainly on the experimental work by Predel and Schwermann. [24] This version shows the presence of three peritectic reactions (see Table 1) with the formation of the (SbSn) phase that exhibits a wide homogeneity range shifting towards Sb-rich compositions at higher temperatures, and the Sb 2 Sn 3 compound that was considered to be stable between 242 and 324°C.…”

“…Recently, three more papers have been published on the Sb-Sn system. Kroupa et al [37] studied Sb-Sn alloys experimentally and through theoretical modelling; they prepared three bulk [18] T,°C [21] T,°C [24] T,°C [27] T,°C [28] T,°C [32] T,°C [33] L ? (Sb) (SbSn) Peritectic 65.2 [24] 420 Before [33] the Sb 3 Sn 4 compound was described as Sb 2 Sn 3…”

Relative Stability of Multiple Bonds between Germanium and Stibium. A Theoretical Study

“…[1][2][3][4][5][6] In particular, germanium-antimony based materials, such as either alloys or glass, have received the greatest attention because of their important semiconducting or optical properties and applications in the electronic industry. [7][8][9][10][11][12] Nevertheless, to the best of our knowledgement, the chemistry of multiple bonds between germanium and antimony still remains unexplored. This is not very surprising since compounds bearing a germanium-stibium multiple bond (such as stibgermenes and stibgermynes) are less stable than the corresponding silicon derivatives, probably due to the differences in their electronegativities.…”
