For those who are curious, I am looking into methods for producing metals thermally for use where reducers such as carbon are not present in high enough concentrations to be useful.

Thanks!

Direct computations, requires full electronic structure calculations coupled with finite temperature effects. I think there was a paper in Phys. Rev. B journal on this calculation for iron oxide. I can try googling it if you are interested.

The paper I mentioned cared more about the transitions in the PO2-PH2O space with little regard to temperature, but it may still be useful:

https://journals.aps.org/prb/abstract/10.1103/PhysRevB.83.094112

An arxiv version of the paper is here:

The key thing is that the decomposition depends on both temperature and oxygen partial pressure. I hope this helps.

Thank you very much for this! This helps a bunch!
