Sample : 86% Sn + 14% Pb (W/W).
Sample mass : 117.2 mg.
Stainless steel crucible.
The temperature is programmed at 2
The melting curve presents two peaks. In fact only pure substances melt presenting a unique peak: generally alloys present a more complex melting curve. In this case Pb an Sn present an entectic at 183.5°C. The end of melting corresponds to the liquids curve. M 119 presents the phase diagram of Pb-Sn system.
