The present article outlines the new databases and developments in calculating and manipulating phase diagrams that have been introduced since the last publication (2009) and briefly describes developments in the programs. The reader who is unfamiliar with FactSage is encouraged to consult these original publications. Articles on FactSage Thermochemical Software and Databases (2002) and FactSage Thermochemical Software and Databases – Recent Developments (2009) have been published in the Calphad Journal. With practice and the assistance of extensive documentation, one can acquire a practical understanding of the principles of thermochemistry, especially as these relate to complex phase equilibria.
While an understanding of chemical thermodynamics is useful in order to run the modules, it is not essential for a user to be an expert in the field. Using today’s personal computers one can calculate and plot phase diagrams within seconds. Forty years ago the turnaround time using a mainframe computer to calculate and print thermochemical tables was measured in hours. and it can calculate and plot binary, ternary and multicomponent phase diagrams with a wide variety of axes. Today FactSage applications include hydrometallurgy, electrometallurgy, corrosion, glass technology, combustion, ceramics, geology, environmental studies, etc. The original F*A*C*T package was designed to simulate the thermochemistry of pyrometallurgical processing and plot classical binary and ternary phase diagrams. Since then FactSage has expanded into a fully integrated thermochemical software and database package that is used worldwide at over 800 sites in universities, governmental and non-governmental research laboratories and industry. In 2001 there was a fusion between F*A*C*T / FACT-Win and ChemSage (formerly SOLGASMIX ) resulting in FactSage®. A principal activity of the CRCT was, and still remains, the promotion and development of the F*A*C*T thermochemical databases and software.ĭuring the 1990s F*A*C*T migrated to personal computers running in a Windows environment. In 1984 the CRCT – Centre for Research in Computational Thermochemistry/Centre de Recherche en Calcul Thermochimique – was founded at École Polytechnique de Montréal. FactSage began in 1976 as F*A*C*T – Facility for the Analysis of Chemical Thermodynamics – a joint research project between McGill University and École Polytechnique de Montréal (Université de Montréal Campus).
