High Aluminium Brick
Products Description
High alumina brick
High alumina bricks have an alumina content greater than 46% and are made from high purity bauxite and clay raw materials. High alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and good resistance to chemical attack by volatile alkanes and certain slags, making them suitable for harsh conditions of use. Through quality control, Xinjia Refractories produces and designs high alumina bricks to meet the requirements of various service conditions.
