White Tabular Alumina
Introduction
Tabular alumina has the characteristics of large and developed hexagonal lamellar α-alumina crystals. Its excellent thermal volume stability and thermal shock properties are attributed to its special microstructure: low open porosity and large crystals, which form closed spherical pores during recrystallization during rapid sintering.
Application
Tabular alumina can be used as the main component of aluminum carbon, aluminum magnesium carbon, magnesium aluminum carbon, magnesium spinel, aluminum chromium refractory brick; It can also be used as a component of alumina rich in high aluminum amorphous refractories.
It can be widely used in iron and steel, casting, ceramics and other industries, and its application in the iron and steel industry almost covers the entire process of making iron and steel.
Advantages
High fire resistance
High corrosion resistance
High slag resistance
High thermal shock resistance
High strength
Good toughness and chemical stability
High corrosion resistance
