Corundum bricks are primarily composed of alumina (Al2O3), which gives them their unique properties. These bricks contain a high percentage of corundum (over 90%), making them one of the most heat-resistant materials available. This composition allows them to maintain structural integrity even at temperatures exceeding 1800°C. Moreover, corundum bricks are highly resistant to chemical wear, erosion, and thermal shock, making them indispensable in various high-temperature furnaces and kilns.
