Bismuth 99.99% is a high-purity, dense metallic element used in pharmaceuticals, low-melting alloys, and radiation shielding. Its low toxicity also makes it a common lead replacement in lead-free solders, free-machining steels and brasses, and shotgun shot. This finely ground 200-mesh powder (CAS 7440-69-9) has a molecular weight of 208.98 g/mol and requires careful handling due to its Danger classification. Store at ambient conditions in a dry environment. Molekula supplies Bismuth 99.99% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
