Algorithm of calculation of multicomponent system eutectics using electronic digital computer

A computer algorithm is proposed for determining low-temperature equilibrium regions for existing phases. The algorithm has been used in calculating nonvariant parameters (temperatures of melting of eutectics and the concentrations of their components) for a series of trinary systems, among which are Ksub(long)Cl, WO4, SO4 (x1=K2WO4; x2=K2SO4), Ag, Cd, Pbsub(long)Cl(x1=CdCl2, x2=PbCl2); Ksub(long)F, Cl, I (x1=KF, x2=KI). The proposed method of calculating eutectics permits the planning of the subsequent experiment in determining the parameters of the eutectics of multicomponent systems and the forecasting of chemical interaction in such systems. The algorithm can be used in calculating systems containing any number of components
