It is very important for a practical purpose to elucidate the kinetics of the heterogeneous reactions which accompany the changes in physical properties of melt, such as viscosity, with the change in composition of melt, e.g., lime slaging and FeO reduction in silicate melt. To contribute to an analysis of such processes, the dissolution of silica cylinder into the sodium silicate melts has been measured at temperatures between 1,100° and 1,300℃ under a static or a rotating condition of the cylinder. It has been observed that the decrease of radius of the cylinder is proportional to the square root of the immersion time under a static condition, and under a rotating condition it is proportional to the immersion time. On the assumption of Stokes-Einstein relationship, non-dimensional treatment of the experimental results reveals that the dissolution process is governed by the diffusion process through the melt. From this treatment interdiffusion coefficients are estimated as follows : [numerical formula]
