What is Lead-Tin Phase Diagram from Cooling Curves about?

This experiment uses cooling curves to establish the phase diagram of the lead-tin binary system. Six lead-tin mixtures are prepared and their cooling curves determined using a thermocouple. The temperature is recorded every quarter minute as each sample cools. The cooling curves are then graphed and the critical temperatures plotted against tin weight percent to derive the experimental Pb-Sn phase diagram. This is compared to the theoretical diagram and sources of error are identified. Improvements to incr
