Composition phase diagrams are <phase diagrams> that also consider variations in composition of a mixture. The most classic of such diagrams are <temperature-composition phase diagrams> for <binary alloys>.


Composition phase diagram

This is the most classical type of phase diagram, widely used when considering a <substance> at a fixed composition.

This is an important man-made <uranium compound> as it is used in <uranium enrichment>.

The main reason for this is that <fluorine> only has one stable <isotope>, which allows you to pick up weight differences in <uranium isotopes> in isolation.
