• Concentration distributions after interdiffusion at 1200 °C were analysed for the diffusion couple of average composition 16Na<SUB>2</SUB>O·12CaO·72SiO<SUB>2</SUB> (wt%) in terms of self-diffusion coefficients of constituent elements. Theoretical calculation was conducted using a multiatomic ion model assuming that Si migrates with oxygens as a silicate ion. The composition of the silicate ion was estimated by determining the parameters in the diffusion equation so as to provide the best fit of the theoretical calculations to the experimental concentration profiles.
