Compact fused alumina is a high grade refractory materials, with the main crystal phase of more than 96%, and porosity of less than 4%.
it has the advantages of good acid and alkali resistance , good wear resistance under high temperature, corrosion resistance and volume stability.
It is widely used in metallurgical, petrochemical, building materials, ceramic and other industries, which are mainly used as refractory ramming mass of blast furnace tapping launder, the castable filling, as well as good materials for the producing steel elongated nozzle, sliding plate and the varieties of corundum bricks.
