Here are some of the features of high alumina bricks:
1.High refractoriness
2.Good load-bearing capacity
3.Resistance to thermal shock
4.Good chemical resistance
5.Good thermal conductivity
In addition to these features, high alumina bricks also have a long service life and can be cut and shaped to meet the specific needs of different applications.
