Coexistence Relations of n+1 Phases in n‐Component Systems

摘要

In an investigation of the coexistence relationships of n+1 phases in the isothermic‐isobaric sections of n‐component systems, Paul A. Beck found that there are at most two coexistence patterns possible. Furthermore, theoretically, only a well‐chosen sample need be examined for the phases it contains in order to clarify the phase coexistence relationships of the n+1 phases whose compositions are already known. The present paper gives formulas for calculating the composition of the ``well‐chosen sample.'' Supplementary formulas are given for the range of coexistence, in the composition space, for any n phases known to coexist.
