is a high-purity form of aluminum oxide that is created by calcining aluminum hydroxide at high temperatures. This process removes any residual moisture and transforms the crystal structure of the aluminum hydroxide into a new form of alumina comprised of large, flat crystals that are virtually free of pores and impurities.

In the steelmaking industry, tabular alumina is used as a refractory lining material in furnaces and kilns that are subjected to extremely high temperatures. It is also used as a coating material on ladles and tundishes to prevent metal contamination and improve the quality of steel production. In the ceramics industry, tabular alumina is used as a raw material in the production of high-performance ceramics such as cutting tools and engine components. Its unique crystal structure and high purity make it an ideal substrate for high strength, wear-resistant ceramics.
