They didn't just want to store data; they wanted to teach a computer to "think" like a chemist. They built a mathematical engine that could take the Gibbs Energy (the energy associated with a chemical reaction) and minimize it. By finding the lowest energy state, the software could predict exactly what would happen when you mixed five different chemicals at 1,600 degrees Celsius.
The "workhorse" of FactSage, it calculates the concentrations of chemical species when a system reaches thermodynamic equilibrium using Gibbs energy minimization.
FactSage is modular, meaning you use different specific tools for different tasks: FactSage FAQ factsage
FactSage (from + Sage ) combines two older systems: FACT (Thermfact/CRCT, Canada) and SGTE (Germany). It calculates equilibrium states of chemical systems using minimisation of Gibbs free energy. It is widely used in:
| Module | Purpose | |--------|---------| | | Browse databases, view compound properties | | Reaction | Stoichiometric thermochemistry (H, S, G, K, etc.) | | Equilib | Calculate multiphase equilibrium (given T, P, composition) | | Phase Diagram | Calculate binary, ternary, pseudo-ternary diagrams | | Mixture | Generate plots (property vs T/composition) | | Data | Modify/create solution databases (advanced) | They didn't just want to store data; they
In the world of metallurgy, there is a saying: "You can't see the future, but you can calculate it."
The fusion of FACT-Win (Canada) and ChemSage (Germany) officially created FactSage. Applications in Modern Science It is widely used in: | Module |
Enter the FactSage engineer. She doesn't need a lab coat; she needs a keyboard. She inputs the composition of the furnace lining and the chemistry of the slag. She hits .
Generates various types of phase mappings, including binary, ternary, and multicomponent diagrams. Reaction Module: Calculates the heat of reaction ( ), entropy ( ), and Gibbs energy ( ) changes for specified chemical reactions.
