Self-diffusion coefficients of oxygen were determined for 40CaO•2OAl2O3•4OSiO2, 16Na2O•12CaO•72SiO2, and 20Na2O•80SiO2 in the liquid state by a gas-liquid exchange technique using 0–18 as the tracer. The activation energies obtained were 54.3, 38.6, and 44.5 kcal/mol, respectively, which were close to those for viscous flow of the respective glasses. The relationship between the oxygen dif fusivity and viscosity was interpreted in accordance with Eyring’s model for viscous flow. Measurements of self-diffusion coefficients of oxygen for the slag and the soda-lime-silica glass were extended through the super-cooled liquid range to the solid state. In both cases the self-dif fusion coefficients showed steep temperature dependence in the temperature range until they finally reached the values reported for their respective solid states. The effect of surface exchange coefficient on the determined self-diffusion coefficient in the gas-liquid exchange technique was discussed.
