Bismuth 99.9% (325 mesh powder) is a high-purity, finely ground metallic element (CAS 7440-69-9) used in pharmaceuticals, cosmetics, low-melting alloys, and semiconductor manufacturing for its unique properties like high density and thermal stability. This ultra-fine powder (molecular weight 208.98 g/mol) requires ambient storage and carries a Danger signal word because it is classified as a flammable solid (H228). Molekula supplies Bismuth 99.9% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
