Popis: Diffusion equations with the diffusion coefficient depending on concentration were solved by the finite difference method. Distributions of sodium oxide concentration and refractive index calculated for an ion-exchanged glass are compared with results measured by electron microprobe analysis and interference microscopy respectively. Even if the interdiffusion coefficients of the ions in the glass vary over long ion exchange times, the error between calculation and measurement can be made as small as possible by selecting an interdiffusion coefficient for a suitable ion exchange time to calculate the concentration distribution in the glass ion-exchanged for a different time.
