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

The phase diagram of the ternary system Ge-Sb-Sn was established by X-ray p owder diffraction and differential scanning calorimetry. No ternary compoun d was found. Two vertical sections were studied in order to follow the reac tion path. Four ternary reactions were characterised: three transition peri tectic (U-type) reactions and one eutectoid (E-type) reaction. Moreover, fr om all equilibrium temperatures, a description of liquidus surface in the w hole composition range is proposed. (C) 2001 Elsevier Science B.V. All righ ts reserved.
