Fused corundum bricks are made by melting alumina in an electric arc furnace and casting it into a model of a specified specific shape. After annealing and heat preservation, the required product is obtained by processing with diamond abrasive tools. This product is divided into three types according to the different crystal forms and quantities of alumina.
