Tabular Alumina
Tabular alumina features high refractoriness, excellent corrosion and scour resistance, strong thermal shock stability, high strength, and stable chemical properties. It is widely used in alumina-based and magnesia-based refractory products, including refractory bricks and unshaped refractories, for steel, foundry, ceramics, and other high-temperature industries.
