A mathematical model of solid-phase chemical synthesis in a binary powder mixture is constructed and studied with allowance for the shrinking of the mixture and the change in the reaction surface as a result of particle caking. Relations are obtained to estimate the number of similar and dissimilar interparticle contacts. Depending on the parameters of the mixture (the stoichiometric ratio between components, the particle size ratio, and the porosity), different modes are revealed that affect the rate of chemical transformation. The optimum conditions for an intense chemical interaction are determined.
