Q What are the storage requirements for aluminum oxide balls?

A
Store in a dry, sealed environment to prevent moisture absorption (especially for active alumina balls).Keep away from strong acids like hydrofluoric acid to avoid corrosion. N o special temperature requirements, but avoid extreme humidity.
Q What are the key characteristics of Aluminum Oxide Balls?

A
1.High hardness (Mohs 9, near diamond).

2.High temperature resistance (>1000°C).

3.Chemical stability (resists most acids/alkalis, except hydrofluoric acid).

4.High surface area (300-350 m²/g for active alumina balls) for adsorption.

5.Uniform sphericity, high density (3.6-3.9 g/cm³ for high alumina balls), and low wear rate (<0.01%).
Q What are the main Applications of Aluminum Oxide Balls?

A
1.Grinding media in ball mills for ceramics, minerals, or paints.

2.Adsorbents/drying agents for gases and liquids (e.g., air, natural gas).

3.Catalyst carriers in petrochemical processes (e.g., hydrogenation).

4.Refractory materials in high-temperature furnaces.

5.Deoxidizers in steelmaking to purify molten metal.
Q What are Aluminum Oxide Balls?

A Answer: Aluminum oxide balls are spherical ceramic particles made primarily of alumina (Al₂O₃, typically >90% purity). They are categorized into active alumina balls (high porosity, for adsorption) and high alumina balls (dense, for grinding or refractory use), produced via processes like spray drying, granulation, and high-temperature sintering.
