Link diagram, environmental conditions and phase stability.

An Ellingham diagram represents the standard free energy of oxidation as a function of temperature. A Pourbaix diagram locates domains of stability in potential–pH; a Chaudron diagram describes in particular equilibria of iron oxides with a reducing gas.
