The significance of the question of corrosion and erosion resistance for refractory materials in direct heating electric furnaces for vitrification of highly active waste (HAW) is substantiated. Algorithms are provided for evaluating their resistance to action of phosphate melts under electric furnace operating conditions. Comparative corrosion tests are performed for refractory materials surpassing Bk-33 objects with respect to quality in melts of aluminophosphate glass with simulation of HAW. Tests results are valuable for selecting lining material in planning ÉP-500 type vitrification electric furnaces with a prolonged service life, and also the next generation of moveable and small-scale melting units.
