Emilio Posted March 15 Share Posted March 15 Hi! Does anybody know if is it possible to add a mineral to the program database? I would like to add crandallite, CaAl3(PO4)(PO3OH)(OH)6. I am trying to generate mineral phase diagrams that include crandallite and apatite. According to the reference attached (Dill, 1991), crandallite should be formed in the presence of HPO4--, Al+++ (Gibbsite), and Ca++ in an aqueous solution (25º C and 1 atm). However, it seems crandallite is missing in the program database.

Jia Wang Posted March 18 Share Posted March 18 Hello, Yes, you can absolutely can use the TEdit application to add reactions and create a custom dataset for your own use. Please see section 9 of the GWB Essentials Guide for more detailed information. You can also view examples on the TEdit webpage. Note that all GWB programs draw their species from the thermodynamic dataset loaded. The default dataset is thermo.tdat. There are different datasets available installed with the software, you can find a summary of the datasets installed here. Hope this helps, Jia Wang Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
