Abstract

The main results of the investigation of the effect of the field strength of various cations on ion diffusion in silicate multicomponent systems are widely used as bonding tool abrasive composite materials of various functional purposes. It is shown that the effective diffusion coefficients of alkali and alkaline-earth cations in the diffusion vapor are not a single-valued function of the ionic radius of the cation, but depend on structural factors and binding energy with other ions of the melt
