Ceramic Beads - Type A 99.3

SiLibeads Type A 99.3 are sintered alumina ceramic grinding beads (≥99.3% Al2O3, so-called "2N" beads) with a size range of 0.2-1.8 mm and specific gravity of ≥3.8 g/cm3, offering a dense structure, matte surface, and high sphericity. They are suited to horizontal and vertical mills for preparing alumina-based technical and engineering ceramics with minimal contamination of the ground material, and also for grinding and dispersing alumina-containing pigments in coatings. Manufactured in Germany by SIGMUND LINDNER GmbH, this pharmaceutical-grade product is supplied, rather than manufactured, by the listing company under in-house standards.
