Refractory High alumina brick is refractory material primarily made from bauxite (Al₂O₃ ≥ 48%) through processes such as crushing, batching, forming, drying, and high-temperature firing. There is excellent Refractoriness and mechanical strength. It is widely used in high-temperature industrial applications. Below is its physical and chemical details:
