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

The phase diagram of the ternary system Ge-Sb-Sn was established by Xray powder diffraction and differential scanning calorimetry. No ternary compound was found. Two vertical sections were studied in order to follow the reaction path. Four ternary reactions were characterised: three transition peritectic (U-type) reactions and one eutectoid (E-type) reaction. Moreover, from all equilibrium temperatures, a description of liquidus surface in the whole composition range is proposed.
