Standard inert ceramic balls are cost-effective, chemically stable packing media manufactured from kaolin clay and silica-rich raw materials. With moderate alumina (Al2O3) content, these balls serve as reliable support media, tower packing, or filler material in non-extreme chemical processes. They provide essential functions such as liquid/gas distribution, catalyst bed support, and void space filling in mild operating environments.
Fired at conventional kiln temperatures, these balls offer:
*Adequate mechanical strength for low-pressure reactors
*Basic chemical resistance to weak acids/alkalis
*Thermal stability for continuous use in medium-temperature processes
*Economic efficiency for large-volume applications
Ideal for: Water treatment, mild gas scrubbing, fertilizer production, and other non-corrosive/low-stress environments where premium high-alumina balls are over-specified.

*Support Bed Base Layer: Under high-alumina balls in reactors to reduce costs
*Packed Towers: CO2 scrubbers, water deaeration, irrigation filtration
*Gas Distributors: Biogas purification, flue gas treatment
*Filler Media: Insulation layers, reactor bottom support
*Protective Barriers: Prevent resin/catalyst leakage in ion-exchange columns
| Advantages | Limitations |
|---|---|
| Low Cost (30-50% cheaper than high-alumina balls) | Unsuitable for temperatures >900°C |
| Adequate Strength for mild pressures | Weak acid/alkali resistance (pH 4-9 only) |
| Rapid Thermal Recovery in cyclic operations | Higher wear rate in abrasive flows |
| Wide Availability in bulk quantities | Not for HF, hot acid, or strong caus |
