Abstract: Zirconia-based refractories, characterized by high refractoriness, good corrosion resistance, and low colorability, are therefore widely used in critical areas of glass furnaces. In view of the severe corrosion of refractories by fluorine-containing opal glass, four refractory materials with different zirconia contents—ZR95, Z80, Z60, and AZS41 were selected and their corrosion resistance using the static crucible method at 1 600 °C for 48 h was investigated in this work. The corrosion behavior was evaluated by combining the dimensional changes at the liquid line and the SEM/EDS interfacial analysis. The results show that the four materials all exhibit low corrosion degrees by opal glass, with ZR95 and Z80 retaining more intact interfaces and demonstrating superior corrosion resistance. After the corrosion test, Z80 displays a slight dimension increase at the liquid line, which may be related to the formation of an adherent surface layer or a protective zirconia-rich layer. These findings can provide a reference for the selection of refractories for furnaces processing fluorine-containing opal glass.
