Abstract

Abstract: With the development of new technologies in industries such as new energy, metallurgy, chemical industry, and waste salt treatment, the erosion of refractory materials used in high-temperature equipment by alkaline melt has become increasingly prominent. Consequently, extensive research has been conducted in this field. This paper reviews the research progress on the alkaline melt erosion resistance of refractory materials, with emphasis on analyzing the advantages and disadvantages of the static crucible method and dynamic methods in different erosion experiments. It discusses the erosion of refractory materials by alkaline melt generated in industrial processes such as new energy, metallurgy, chemical industry, and waste salt treatment. Furthermore, it reviews the alkaline melt erosion resistance behavior and mechanisms of MgO-based refractories, Al₂O₃-SiO₂-based refractories, Cr₂O₃-based refractories, and ZrO₂-based refractories. The aim is to provide a theoretical basis and technical reference for understanding the erosion behavior of alkaline melts, optimizing the design of refractory materials, and enhancing the service life of high-temperature equipment.

Key words: refractory material, alkaline melt, erosion method, erosion mechanism, interface behavior
