# Thermodynamic Stability

- [Energy Corrections](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/thermodynamic-stability.md): How energy adjustments and corrections are calculated on the Materials Project (MP) website.
- [Anion and GGA/GGA+U Mixing](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/thermodynamic-stability/anion-and-gga-gga+u-mixing.md): Details on anion and GGA/GGA+U mixing scheme corrections
- [GGA/GGA+U/r2SCAN Mixing](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/thermodynamic-stability/gga-gga+u-r2scan-mixing.md): Details on the GGA/GGA+U/r2SCAN mixing scheme corrections
- [Adding Energy Corrections to Custom Entries](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/thermodynamic-stability/adding-energy-corrections-to-custom-entries.md)
- [Phase Diagrams (PDs)](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/phase-diagrams-pds.md): A description of the methodology for constructing and interpreting compositional phase diagrams from the Materials Project (MP) website and API.
- [Chemical Potential Diagrams (CPDs)](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/chemical-potential-diagrams-cpds.md): Overview of how chemical potential diagrams (CPDs) are constructed and visualized. These are available as part of the Phase Diagram App.
- [Finite Temperature Estimation](https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability/finite-temperature-estimation.md): Description of the methodology used to estimate Gibbs free energies of formation at finite (T>0 K) temperature. This is an option available within the Phase Diagram App.
