Activated Alumina Balls
(B) Physical Properties
Equilibrium static water adsorption capacity at 60%RH & 30oC,% = 18-21%
Free moisture at 120 oC, % = 2% max.
Tapped bulk density,kg/m3 = 800-850kg/m3.
Pore volume,cc/gm. = 0. 4 min.
Surface area, m2/gm. = 350min.
Loss on ignition (250-1000 oC) = 5-7%.
(C) Chemcial Compostion
Al2O3 = 93% min.
Fe2O3 = 0. 1% max.
Na2O = 0. 3% max.
SiO2 = 0. 1% max.
1. The mechanical & physical properties varies with the size of balls.
2. Product can also be manufactured with other specifications as per requirements.
