6.4 Determination of ternary intrinsic diffusion coefficients with inert markers

Abstract

This chapter discusses determination of ternary intrinsic diffusion coefficients with inert markers. The inert markers placed initially at the vapor-solid interfaces get embedded in the diffusion disks, remain close to the interface and are found at compositions close to that of the interface. Schematic concentration profiles for a vapor-solid couple with the inert markers employed in the determination of intrinsic diffusion coefficients are provided. Cumulative intrinsic flux (Ai) can be determined graphically from appropriate areas under the profiles (Heumann's method).
