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

{tag=Alloy}

An alloy of <iron> and <carbon>. Because such allys have had such incredible historical importance due to their different properties, different <phases> of <Fe-C> have well known names such as <steel>

"Water" is the name for both:
* the <chemical compound> with <#chemical formula> H\sub[2]O
* the <liquid phase> of the <chemical substance> composed of the above <chemical compound>
