Description

This plot shows that CaO crystallizes more as the melt develops, coherent with the logic that as a melt begins to crystallize, first the elements with the smaller atomic radii will crystallize, followed by the replacement of larger atomic radii elements as per maneuvering thermodynamic equilibrium. It could be concluded that the CaO replaces the alkalis further into the evolution of the melt.
