What are Alumina Balls?
Alumina Balls Composition
Ceramic Alumina balls are manufactured from refined aluminum oxide powders, shaped and sintered under controlled conditions to achieve stable chemical and structural properties. The composition is primarily Al₂O₃, with purity grades available from 68% to 99.7%.
Medium alumina (68–80%) contains balanced proportions of Al₂O₃ and auxiliary oxides, often applied in cost-sensitive grinding operations.
High alumina (92–95%) features minimized silica and alkali content, ensuring reliable chemical inertness for catalyst and filtration uses.
Ultra-high purity (99%–99.7%) is produced with minimal impurities, offering excellent stability for thermal storage and electronic ceramics.
Extended service life and low contamination in milling and grinding.
Reliable support media for petrochemical and chemical reactors.
Proven durability in high-temperature and regenerative systems.
Resistant to acids, alkalis, and solvents, ensuring long-term stability in catalytic and filtration applications.
Alumina Ball Manufacturing Process
The manufacturing process of alumina oxide balls (Al₂O₃) follows a series of controlled steps designed to achieve consistent high density, mechanical strength, and material purity.
1. High-grade aluminium oxide (Al₂O₃) powder is selected as the primary raw material.
2. For activated alumina balls, additional processing is applied to create porosity and high surface area.
1. Alumina powder is mixed with binders and water, then shaped into spheres by granulation, extrusion, or rolling machines.
2. Diameters typically range from 1 mm to 90 mm, including mini balls for precision applications.
Formed balls are dried under controlled conditions to remove moisture and stabilize the green body.
1. At temperatures of ≥1600–1700 °C, the balls are sintered to achieve high density, mechanical strength, and thermal resistance.
2. For activated alumina balls, a special activation step introduces porous structures for adsorption functions.
