The following discussion took place during May 1999.

 

**************************************************************************

I need to generate a model of the behavior of Fe++ and Fe+++ at high temperatures and I have been told that SUPCRIT might be able to help me. Would anyone have access to, or know how
to get access to, this program?

I have searched the web and found nothing. Any help would be appreciated.

Dear Paige,

I have a DOS version of SUPCRIT92. Obviously, you will wish to use the version for Win95, mentioned by David Norman. However, if you want, I could send you the DOS version. However, I should note that the SUPCRIT92 database contains a little data on Fe ions (only Fe+2, Fe+3, FeCl+, FeCl2). Properties of fero- and ferric hydroxo-complexes are absent. So, these data are very truncated and (I think) not suitable for your calculations. Surely, you can use the code, but I think you should to search more completed dataset on Fe ions. Perhaps, you can find necessary data in papers of E.L.Shock, D.A.Sverjensky, J.Schott and some other authors (look for Geochem.Cosmochem.Acta, Chem.Geol., Amer.J.Sci.).

Cheers,
Pavel Azimov.
