Phase Diagrams and Lever Rule - Penji app Here is an example of a phase diagram for an SiO₂ and Al₂O₃ mixture. On the x axis, we have the mole % of Al₂O₃ in the mixture. As you go from left to right, you are increasing the amount of Al₂O₃ in the mixture, and the corresponding percentage is the mole fraction (number of moles of Al₂O₃ divided by the total number of moles) of the mixture.
