bappy Posted September 13, 2013 Share Posted September 13, 2013 This question has been asked before - but under a different moderator. Perhaps you can help Brian? What is the phase FeO© in the thermo.dat ? thanks! Quote Link to comment Share on other sites More sharing options...
bappy Posted September 13, 2013 Author Share Posted September 13, 2013 It should be FeO - c in parentheses. Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted September 13, 2013 Share Posted September 13, 2013 Hi bappy, I'm afraid I don't know any more about it than you do. It appears to be a ferrous oxide mineral, perhaps somewhat similar to Wustite, though I can't say for sure. If you look in thermo.com.V8.R6+.dat, you'll find a very similar entry simply called FeO (I'd bet they're the same) with a reference listed. Perhaps you could track down the original source of the entry. FeO type= formula= mole vol.= 12.000 cc mole wt.= 71.8464 g 3 species in reaction -2.0000 H+ 1.0000 Fe++ 1.0000 H2O 15.2277 13.5318 11.5796 9.7985 8.0384 6.6249 5.4341 4.3762 * gflag = 1 [reported delG0f used] * extrapolation algorithm: supcrt92 [92joh/oel] * reference-state data source = 78hel/del * delG0f = -60.097 kcal/mol * delH0f = -65.020 kcal/mol * S0PrTr = 14.520 cal/(mol*K) 78hel/del Helgeson, H.C., Delany, J.M., Nesbitt, H.W., and Bird, D.K., 1978, Summary and critique of the thermodynamic properties of rock-forming minerals: Amer.
