23% Inert Ceramic Ball – Catalyst Support Media

JXKELLEY 23%AL2O3 Inert Alumina Ceramic Ball (Catalyst Support Media) are used to fill and support the catalyst layer in catalytic columns and reactors. The balls are made of high quality solid pressed silicate porcelain with an aluminum oxide content of Al2O3 – 23% (in the range of 23-26%). They have high mechanical strength, resistance to acid, alkali, and some organic solvent, and resistance to thermal shock, which makes them all ideal choice for support of all types of catalysts. Inert Ceramic Balls for Catalyst Bed Support Media are available to the order of sizes from 3 mm to 50 mm in diameter (1/8 – 2 inch).
