Electric fused zirconia corundum bricks are divided into 33 #, 36 #, and 41 # bricks based on the content of ZrO2. The main mineral phases are plagioclase zircon, corundum, and glass phases. The plagioclase zircon crystals form the backbone of the brick body. ZrO2 has a high melting point (2715 ℃), good chemical stability, and strong corrosion resistance to acidic and alkaline media, especially glass liquid. With the increase of ZrO2 content, the product performance is further improved.
Electric fused zirconia corundum bricks are mainly used in the pool walls, slag, breast walls and other parts of glass furnaces, and have achieved good results in use
