The Regularities of the High-Temperature Reaction of Graphite during Diffusion of the Solid Phase

Abstract

On the basis of the laboratory findings on the interaction of graphite with carbon dioxide at high temperatures - up to 3200K - it was established that at temperatures greater than 2500K the process of the diffusion carrying out of carbon from the volume of a solid body to the reacting surface begins to be exhibited. The regularities of this process have been studied. An analytical analysis is made of the process of the diffusion of graphite for the conditions of one-dimensional nonstationary diffusion. The coefficient of self- diffusion of carbon and its temperature dependence for the range 2800-3300K have been determined.
