It is a transitional phase patterns of alumina, which is the main phase of ρ alumina, the main component of AL2O3. ρ- alumina using aluminum hydroxide by suspension firing rapid dehydration, and chilled prepared, generally a specific surface area 200 m2 / g or more, it has a strong activity and water absorption, and a certain hydration activity.
use:
1, can replace calcium aluminate cement used for high unshaped refractory castable binder, also can replace silicon powder and ultrafine alumina powder, corundum products for high-grade adhesives and binders.
2, can be used as an adsorbent, absorbent agent activated alumina, a catalyst carrier, widely used in petroleum, chemical, pharmaceutical, health and other industries.
