It is vexatious for conventional methods to calculate the compositions of equilibrium system with many components and minor components. For that, the element potential method (EPM) for composition calculation in multi-phase equilibrium system was deducted based on the principle of Gibbs free energy minimization and the law of mass conservation, by introducing Lagrange factor lambdae and the concept...
Chemical equilibrium calculation program for metamorphic petrology, FLASK-SG, was written for Unix variants (Linux, IRIX, Tru64 UNIX). It is also ported to Windows 95/98. The user specifies a temperature, pressure, and substance amounts (in moles of any chemical formula in C-H-O-Si-Al-Ti-Fe-Mn-Mg-Ca-Na-K system) to this program, then it calculates the stable mineral assemblage, mineral amounts, and...
