Solid-Solid-Liquid Phase Diagrams: ConcepTest and Example Problem
Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.
Example Problem 1
Determine the mole fraction in equilibrium of the liquid in the liquid-solid Si phase at the point shown on the graph.
overall composition, zSi =0.70, xSi in liquid = 0.62, xSi in solid = 1.0
