Aluminum carbon bricks are mainly composite refractory materials produced by combining alumina (such as sintered/fused white corundum, sub-white corundum, brown corundum, plate-shaped alumina, sintered bauxite, etc.) and carbon/graphite raw materials. In most cases, additives (such as SiC, Si, Al, etc.) are also added to improve their performance. According to the production method, Al2O3-C refractories can …
