Fused cast high alumina bricks are also known as fused zirconia bricks. The zirconia content is 93-96%. The mineral phase is mainly clinozoite. Zirconia is the strongest oxide resistant to the corrosion of liquid glass. The fused cast zirconia bricks are suitable for various glass furnaces, especially for kilns producing high-grade glass, and the use effect is more obvious. For example, borosilicate glass kilns, aluminosilicate glass kilns, and non-ferrous metal smelting electrolyzers
The electric fused high zirconium brick has a very compact structure, low apparent porosity, high strength, excellent wear resistance, erosion resistance, and resistance to liquid glass corrosion. It hardly produces stones and streaks during use, and does not pollute the liquid glass. It is often used in key parts of glass furnaces
