Study of diffusion processes in low-temperature thermopiles
Abstract
The paper describes the kinetics of formation as well as the qualitative and quantitative chemical analysis of the composition of the reactive diffusion layer in a (Bi,Sb)2Te3-Co contact with respect to the hot junction of a low-temperature thermal battery. An expression is presented for the relation between the diffusion coefficient and the temperature. The results of the quantitative analysis of the diffusion layer are found to correspond to the phase equilibrium of the Ca-Sb-Te system.
