# 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.materialsproject.org/methodology/materials-methodology/thermodynamic-stability.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
