FactSage 8.3 is the latest major release of the industry-leading integrated thermochemical software and database package developed by Thermfact/CRCT (Montreal) and GTT-Technologies (Aachen). This powerful tool computes complex multiphase equilibria, phase diagrams, thermodynamic properties, and process simulations in materials science, metallurgy, ceramics, geochemistry, and chemical engineering. With extensive database expansions, new process simulation add-ons, and user-friendly enhancements, FactSage 8.4 supports accurate predictions for high-temperature systems, alloy design, slag modeling, ionic organics, and more—enabling researchers, engineers, and educators to optimize materials processing and reduce experimental costs.

Key Features of FactSage 8.3

• New Process Simulation Add-ons: FactFlow for rapid graphical design, analysis, and optimization of process flowsheets; FactProSim for local-equilibrium simulations using the EERZ approach with seamless Excel integration—ideal for steelmaking, refining, and industrial processes (not available in network client installations).
• Industrial Alloy Integration in Equilib: Directly select and define real-world industrial alloy grades (e.g., aluminum, copper, magnesium) in the Reactants Window for realistic composition-based calculations.
• Major Database Expansions and Updates:
  • FactPS: Added 165 new compounds; total now exceeds previous counts with enhanced pure substance data.
  • FToxid: New optimizations for K-Fe, Sn-containing, and Zr-Na systems; added solid solutions like (Zr,Ti,Sn)O2 orthorhombic and Sn-spinel; expanded phases (e.g., Nepheline, Leucite, Kalsilite with Fe additions).
  • New Databases: FTionx (FACT Ionic Organics Database) for ionic organic systems; SGTE(2024) updated alloy database.
  • Other updates: FTlite, FTsalt, FScopp, FSlead, FSstel, FTmisc, SpMCBN (nearly 100 new ternary systems), GTOx, and more.
