Capillary Phenomena in a Binary Two-Phase System

Similar to the case of a single component system, Eq. (15.2) can be expressed in terms of bulk chemical potentials and interfacial energy as 

In general, v is a function of X but it can be considered to be a constant for a small variation in X. Since the value of Eq. (15.8) is much smaller than 1 for a particle with a radius greater than 0.1 pm at a usual liquid phase sintering temperature, Eq. (15.8) can be written as 

Equation (15.10) was derived for systems where a and are solutions of A and B. However, this equation can also be applied to systems where a is an intermediate compound, AyB, and is a liquid or a solid solution. In this case, X A expressed as
