Tabular alumina is a pure sintered alumina, thoroughly calcined without the addition of any additives such as MgO or B2O3. It boasts a coarse, well-developed α-Al2O3 crystal structure, with an Al2O3 content exceeding 99%. Characterized by a plate-like crystal structure and numerous closed pores, its purity, high thermal stability, and minimal reheating shrinkage contribute to its exceptional properties. After high-temperature treatment, it exhibits excellent thermal shock resistance and flexural strength.
Tabular alumina characteristics: high refractoriness; excellent corrosion resistance; superior erosion resistance; exceptional thermal shock resistance; high strength and good toughness; stable chemical properties.
Tabular alumina finds diverse applications, serving as a primary component in refractory materials like alumina-carbon, alumina-magnesia-carbon, magnesia-alumina-carbon, magnesia-spinel, and alumina-chrome refractory bricks. It is also utilized to enrich the alumina content in high-alumina shaped refractory materials. Its widespread use spans industries such as steelmaking, foundries, ceramics, and beyond, with extensive application throughout the entire iron and steel production process.
