Tabular alumina is a high-level synthetic refractory raw material, characterized by its superior performance advantages, including high refractoriness, low alkali content, high strength, high thermal shock resistance, excellent slag attack resistance and high-temperature volumetric stability. These advantages are attributed to its engineered microstructure, featured in well-developed crystal grains and uniformly distributed intracrystalline micropores.
