Prediction of the diffusing component(s) in a solid-solid reaction system
Abstract For designing a process including a specific solid-solid reaction, knowledge of the diffusion mode is necessary, i.e., which is the diffusing component(s). No such prediction methods, however, have thus far been available. In the present paper, a simple empirical method is successfully examined for inorganic solid-solid reactions, by using only the physical properties of the reacting components, i.e. the coordination number and the ionic radii.
