Ceramic Beads - Type A 99.99

SiLibeads Type A 99.99 are sintered high-purity alumina ceramic grinding beads (≥99.99% Al2O3, so-called "4N" beads), sized 0.2-1.8 mm with a specific gravity of ≥3.8 g/cm3. Their dense, sintered structure, matte surface, and high sphericity make them suited to horizontal and vertical mills for producing alumina-based technical and engineering ceramics with minimal media contamination, as well as for dispersing alumina-containing pigments in coatings. Manufactured in Germany by SIGMUND LINDNER GmbH and offered here in pharmaceutical grade under in-house standards.
