Abstract
A new and rapid computer method for the calculation of phase boundaries in multicomponent systems is described and its application is demonstrated by a determination of the liquid-state miscibility gaps in the ternary system Pb-Cd-Zn and the quaternary system Pb-Cd-Zn-Sn. Provided that the necessary thermodynamic data have been determined or can be calculated, the method is of general application to systems of n components splitting into p (≤ n) phases.
