Aluminium Oxide Ceramic Beads
Sintered SiLibeads® Type A 99.99 grinding beads are high-purity aluminium oxide ceramic beads with an aluminium oxide content of 99.99% (Al2O3), also known as ‘4N’ beads. These beads have a specific gravity of ≥ 3.8 g/cm³ and are manufactured using a special sintering process that ensures a dense structure and excellent mechanical properties.

Details
Available sizes
- Standard sizes: 0.2 mm to 0.6 mm
- Fraction widths: 0.1 mm (0.2 mm to 0.4 mm) and 0.2 mm (0.4 mm to 1.6 mm)
- Special sizes and fractions: Available on request
Applications
- Ceramic industry:
- Technical and optical ceramic components: Particularly suitable for raw material processing, as the high aluminium oxide content minimises contamination from foreign abrasion. This results in almost autogenous grinding.
- Battery materials: Processing of raw materials used in parts of lithium-ion, sodium-ion or solid-state electrolyte batteries.
- Colour industry:
- Colour systems with aluminium oxide: Ideal for grinding and dispersing aluminium oxide-containing colour systems, both with inorganic and organic pigments.
- Suspensions: Thanks to their low specific weight (3.8 g/cm³), the grinding balls are particularly suitable for processing suspensions with low to medium viscosity.
Quality characteristics
- Finely ground raw materials: The use of ultra-fine raw materials and a customised sintering process guarantee a dense structure.
- Surface and roundness: The beads have a smooth surface and high roundness, which contributes to optimum mechanical properties.
- Grinding and cost efficiency: The combination of outstanding bead quality and carefully coordinated selection of bead and particle sizes of the ground material results in high grinding efficiency.
