Summary:This work justifies the practical importance of corrosion and erosion resistance of refractories during the design of direct electric heating furnaces used for the vitrification of high-level waste (HLW). The major promising materials are listed, and an algorithm for assessing their resistance to borosilicate melts during the electric furnace operation is provided. Corrosion testing of the refractories was performed in static and dynamic conditions in a low-melting borosilicate glass melt with and without simulated liquid HLW. Refractory materials were selected with the highest resistance in conditions mimicking a glass melt containing solidifying HLW. The results will be used to guide the choice of the lining material during the design of removable and small-scale melters.
