Inert ceramic (porcelain) balls are used to fill and support the catalyst layer in catalytic columns and reactors, and as grinding bodies in ball mills.
The balls are made of high quality solid pressed silicate porcelain with an aluminum oxide content of Al2O3 -92% (in the range of 92~99%). 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.
Ceramic Balls are available to the order of sizes from 3 mm to 50 mm in diameter. Other types of ceramic products can be made upon your request indicating the necessary technical data.
Chemical compostion for 17% alumina ceramic ball:
| Al2O3+SiO2 | Al2O3 | Fe2O3 | MgO | K2O+Na2O +CaO | Other |
| > 93% | 17-19% | <1% | <0.5% | <4% | <1% |
| Al2O3+SiO2 | Al2O3 | SiO2 | Fe2O3 | MgO | K2O+Na2O+CaO | Other |
| > 92% | 23-26% | 68-73% | <1% | <2.5% | <4% | <0.5% |
Leach able Fe2O3 is less than 0.1%
