SiLibeads® Ceramic Beads
SiLibeads® Type A 99.3
Our sintered SiLibeads® Type A 99.3 grinding beads are high-quality aluminium oxide ceramic beads with an aluminium oxide content of 99.3% (Al2O3). Due to their dense structure and excellent mechanical properties, these ‘2N’ beads are ideal for numerous industrial applications, particularly in the ceramics and paint industries.
Aluminium oxide ceramic beads
SiLibeads® Type A 99.3 beads are characterised by a specific weight of ≥ 3.8 g/cm³ and precise manufacturing. The special sintering process gives the beads a dense structure, ensuring high breakage resistance and a long service life. Their smooth surface and high roundness optimise their mechanical properties, resulting in a uniform grinding process.

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 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 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.
Special sizes and fractions are available on request for specific application requirements. This flexibility allows the grinding beads to be optimally adapted to individual process requirements, thereby contributing to a further increase in efficiency and quality. SiLibeads® Type A 99.3 aluminium oxide ceramic beads offer an optimal solution for demanding grinding processes in the ceramics and paint industry thanks to their high purity, mechanical stability and tailor-made adaptability.
