Inert Alumina Ceramic Ball
99% alumina inert ceramic balls for catalyst and adsorbent bed support in high-temperature, steam and silica-sensitive service.
Which Inert Ceramic Ball grade do you need?
Choose alumina content by temperature and chemistry: standard grades for dryers and adsorbers, high-alumina and 99% grades where high temperature, steam or silica leaching is a concern.
| Grade | Key property | Typical use |
|---|---|---|
| Standard inert ceramic ball | Economical, good crush strength | Dryer and adsorber bed support |
| High-alumina ceramic ball | Higher strength and temperature resistance | Hydrotreating and reforming reactors |
| 99% alumina ceramic ball | Lowest silica leaching, highest thermal stability | High-temperature, steam and silica-sensitive service |
| Graded bed | Layers of decreasing size above and below the bed | Holds media in place and distributes flow |
Where is Inert Ceramic Ball used?
Inert ceramic balls are used as the support and top layers of fixed beds in refineries, gas plants and air separation units.
- Air separation pre-purification — support layer under 13X APG and activated alumina
- Natural gas dehydration — support and hold-down layers in sieve dryers
- Compressed air drying — bed support in desiccant dryers
- Refinery and petrochemical reactors — 99% alumina balls for catalyst beds
How is Inert Ceramic Ball manufactured and tested?
We make inert ceramic balls in our own Henan plant — batching, forming, high-temperature sintering and size grading — and test each lot before it ships with a COA.
- Batching — alumina and clay raw materials blended to the target Al₂O₃ content.
- Forming — rolled into balls from 3 to 50 mm.
- Sintering — fired in high-temperature kilns for strength and chemical stability.
- Lot testing — crush strength, water absorption, acid and alkali resistance, Al₂O₃ content.
- Capacity and quality system — 10,000 t per year under ISO-certified quality management.
