How can I know if an entry from the mp-api is stable around room temperature?

pymatgen

Are there any features that can provide such information? I do not care about materials that can exist only at low temperature, such as high-temperature superconductors.I just want materials that are stable around room temperature.

Hi @Leonard_Bruce, yes there’s an approximation for finite temperature on the MP phase diagram app. If you don’t know a priori which chemical systems are of interest to you (e.g., you just want all stable materials a a given temperature), then you should look into the PhaseDiagram class in pymatgen - this is what we use to build phase diagrams from MP thermo entries.

Thanks @Aaron_Kaplan. I have read the links you provided and this Phase Diagrams (PDs) | MP Public Docs (materialsproject.org) too, and I got one more question.

Are there any easier ways of knowing the approximations for finite temperature? In other words, can I know the approximations through mp-api if all I got is the mp-ids? If this is possible, could you please give me some code snippets, cause after all, I am not quite familiar with the Phase Diagram APP or the PhaseDiagram class.
