High Alumina Bricks
![高铝砖](http://www.sdrobert.com/uploads/高铝砖2.jpg)
Product Information
High aluminum bricks refer to alumina content in more than 48% of a neutral refractory material, according to the different aluminum content, mainly divided into three levels: Ⅰ(Al2O3≥75%); Ⅱ(60%≤Al2O3<75%); Ⅲ(48%≤Al2O3<60%).
Features
1. Good high temperature performance
2. Good resistance to spalling
3. Small creep at high temperature
4. High thermal stability(refractoriness above 1770℃)
5. Good slag resistance
