Effect of temperature on the corrosion of refractories in glass melts (review)

The temperature of interaction with the melt is the most important factor determining the rate at which a refractory is corroded by glass. The work of other authors in mathematically describing the effect of temperature on corrosion rate was considered by attempting to ascertain the degree to which their results obey the Arrhenius equation. For this purpose the published data were plotted in log K-1/T coordinates, where K is the corrosion rate and T is the temperature. The activation energy of the process was calculated if the dependence satisfactorily approximated to a straight line. It was shown that the Arrhenius equation can be used to describe the temperature dependence of corrosion. The activation energy values, calculated from the published data, information about the refractory materials and glasses studied, as well as the experimental conditions employed, are tabulated and discussed. Comparisons are made. 16 refs.
