Programs based on minimizing free energy

CHEMSAGE (ESM (Engineering and Materials Science) Software, http //www.esm-software.com/chemsage/) is a program family based on the minimization of the Gibbs energy and distributed commercially. 

As successor of SOLGASMIX (Besmann 1977), CHEMSAGE is mainly used for technical concerns, e g. development of alloys, ceramics, semiconductors and superconductors, material processing, and investigation of material behavior. 

Dynamic reactions like processes in blast furnaces, roasting processes or the solidification of liquid alloys can be simulated using the REACTOR MODEL 

MODULE. Raw material and energy are input parameters. From this reactions in gaseous and condensed phases are simulated under different boundary conditions as well flux of material in different parts of the reactor. 

According to the distributor, it is also possible to address geochemical problems, environmental pollution in soil, air and water, and impact of toxic, nontoxic and radioactive waste disposals with the implementation of several modules from the program SUPCRT 92 (Johnson et al. 1992).
