Refractory ceramic block has been used in glass vitrification furnaces for nuclear waste for decades. Corrosion estimates based on laboratory testing is known to be conservative and a more systematic testing protocol and predictive understanding of the refractory lifetime in a service melter is of interest to reducing mission duration and costs. In this work, an experimental matrix was developed to establish key factors that control Monofrax® K-3 corrosion in contact with simulated Hanford glasses. Crucible-scale corrosion tests were conducted following guidelines from ASTM C621. Refractory loss as a function of temperature and time were measured to evaluate corrosion under those conditions. The initial corrosion test results indicated that the glass melt surface properties may dominate the melting line corrosion.
