Resistant balls are refractory ceramic spheres manufactured from industrial alumina and refractory kaolin, forming an Al2O3‑based ceramic matrix. The product grades range from ordinary refractory balls with alumina content of 45‑90 % to high‑aluminium balls containing up to 98 % alumina, providing resistance to temperatures above 1200 °C. The balls exhibit low chemical activity, high mechanical strength and excellent resistance to thermal shock, oxidation and acid‑alkali corrosion.
Typical industry specifications include a silicon content between 0.5 % and 5 % and iron content below 1 %, which influence the thermal expansion and sintering behaviour. Bulk density values are usually 2.2‑2.8 g/cm³ and the specific surface area falls in the 200‑220 m²/kg range. Size distribution is commonly offered from 5 mm up to 25 mm, with tolerances of ±0.1 mm for precision applications.
These balls are employed as catalyst supports, furnace packing material and thermal‑insulation media in petrochemical, steel and glass production. Users such as refinery operators, cement plants and urea manufacturers select the appropriate grade for their high‑temperature reactors or reforming furnaces. The supplier ships the product in bulk bags or drums, accepts custom grade specifications and negotiates trade terms on a case‑by‑case basis.

Importers should first obtain a material safety data sheet and verify the exact alumina and silicon percentages for the intended grade. Request a sample batch to assess particle size distribution and bulk density before committing to a large order.
Logistics details such as production lead time, chosen incoterm (e.g., FOB, CIF) and acceptable payment methods are not listed. Confirm these points with the supplier, and ensure that the packaging format (bulk bag or drum) aligns with your freight planning.
For quality assurance, arrange a third‑party inspection that checks dimensional tolerances, bulk density and surface area. Ask the supplier to provide an inspection report and any available test certificates to validate that the balls meet your process specifications.
