Product Features

• Composed of interlocked tabular α‑alumina crystals with compact structure, featuring high bulk density, superior mechanical strength and excellent abrasion resistance.

• High alumina purity and low impurity content endow high refractoriness, minimal liquid phase formation at elevated temperature and outstanding high‑temperature dimensional stability.

• Dominated by closed pores in microstructure, delivering superior thermal shock resistance and slag corrosion resistance against cracking and spalling under high‑temperature service.

Application Fields

• Steelmaking industry: monolithic refractories, purging plugs, nozzles for ladles, tundishes and electric arc furnaces.

• High‑temperature kilns: lining materials, precast blocks and ramming mixes for various industrial furnaces.

• Advanced manufacturing: high‑grade wear‑resistant aggregates and raw materials for special industrial ceramics.
