Abstract
In the previous paper, the authors have theoretically introduced a judgment method to determine the diffusing component of a specific solid-solid reaction system, based on the dependence of the reaction rate upon particle size ratio. The method is actually applied to some reaction systems in the present paper, and the results agree well with the observed results.
Furthermore, a simple prediction method without experiment is sought, using only the physical properties of reacting components; e. g., the ionic radius and the atomic coordination number. The present method is satisfactorily confirmed by a lot of observations so far reported, with the probability of 91%.
