Solid samples of (Ge15Te85)l-kSnk and (SnkGel−k)15Te85 ternary alloys with different tin concentrations were obtained from the liquid state at different initial temperatures (T0) by the splat cooling technique. They were analized by X-ray diffraction and Mössbauer spectroscopy. The results were compared with results obtained in similar studies on slowly cooled and annealed samples. The previous observation that increasing tin concentration renders the formation of the amorphous phase more difficult, is confirmed. For a fixed k, and T0 < 800 °C, the higher T0 the easier the glassy phase is obtained. This behaviour reverses for T0 > 800 °C.
