Products Description








High Alumina Brick
High-alumina brick refers to a neutral refractory material with an alumina content of more than 48%. According to the different aluminum content, it is mainly divided into three grades: grade I (Al2O3≥75%) grade II (60%≤Al2O3<75% ) Grade III (48%≤Al2O3<60%).
