The corundum brick's Al2O3 content is as high as 90% . For its better characters, the corudum brick often be used in petrochemical industry furnace, gasification furnace and large fertilizer equipment, and more than 1600° C super high temperature furnace, liner of furnace. It has longer Service life and it is reliable in quality.
