Describe of Inert Ceramic Alumina Ball-17% Al2O3
Inert Ceramic Alumina Balls with 17% Al₂O₃ are widely used as catalyst bed support media in various chemical, petrochemical, and environmental applications. These balls are made from high-quality raw materials, primarily alumina and kaolin clay, ensuring excellent mechanical strength and chemical stability.
Key Characteristics:
- Alumina Content: Approximately 17% Al₂O₃ 
- Shape: Spherical 
- Color: White to light gray 
- Size Range: Commonly available in sizes from 3mm to 50mm (custom sizes available) 
- Bulk Density: ~1.35–1.40 g/cm³ 
- Crush Strength: High, depending on size 
- Water Absorption: ≤5% 
- Thermal Resistance: Withstands rapid temperature changes and high operating temperatures up to 1000°C 
- Chemical Stability: Excellent resistance to acid, alkali, and organic solvents
