High alumina brick
High alumina brick is a kind of refractory material. The main component of this refractory brick is Al₂O₃.
If the Al₂O₃ content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries stipulate that the lower limit of Al₂O₃ content for high aluminum refractory is 42%. In China, the Al₂O₃ content in high-alumina bricks is usually divided into three grades: Ⅰ etc.-Al₂O₃ content> 75%; Ⅱ etc.-Al₂O₃ content is 60 ~ 75%; Ⅲ etc.-Al₂O₃ content is 48 ~ 60%.
