Description of High Alumina Refractory Bricks With 80% Al2O3 & 1800℃ Refractoriness For Furnaces And Kilns

High alumina bricks are a type of refractory brick that contains a high percentage of aluminum oxide (Al2O3). They are typically made from bauxite, a naturally occurring mineral that is rich in Al2O3. High alumina bricks are characterized by their excellent high-temperature performance, corrosion resistance, and mechanical strength.
