1. The problem statement, all variables and given/known data Just sketch the solid-liquid phase diagram from the data. the following data was collected from a cooling curve of the mixed metal oxide system XO-ZO, where X and Z are metals. 2. Relevant equations 3. The attempt at a solution I don't understand why the temperatures are called "halt" and "break" but I came up with this diagram. My professor and the text book don't explain how to make these diagrams so I'm totally lost. Can someone check this and if its wrong help me correct it?
