The fused cast high alumina brick is also known as the electrofused zirconia brick. The zirconia content is 93-96%, and the mineral phase is mainly oblique zircon. Zirconia is the oxide with the strongest resistance to the erosion of molten glass. The fused cast zirconia brick is suitable for various glass furnaces, especially for furnaces producing high-grade glass. The use effect is more obvious. For example, borosilicate glass furnace, aluminosilicate glass furnace, and non-ferrous metal smelting electrolytic cell
The fused high zirconium brick is very compact in structure, low in apparent porosity and high in strength. It has very good wear resistance, erosion resistance and glass erosion resistance. It hardly produces stones and streaks in the process of use, and has no pollution to the glass. It is often used in the key parts of glass kilns
