Bismuth

Bismuth (CAS 7440-69-9 ), abbreviated Bi, is a post-transition metal sourced and traded in elemental form for use across pharmaceutical synthesis, polymer manufacturing, and metallurgical processing.

It functions as a low-toxicity alternative to lead and other heavy metals in applications where regulatory pressure or end-product safety requirements demand cleaner substitutes.

In pharmaceuticals, elemental bismuth serves as a precursor to active bismuth salts and compounds used in gastrointestinal formulations and antimicrobial preparations.

Polymer manufacturers incorporate it into flame-retardant systems where halogen-free compliance is required, particularly in wire, cable, and electronic component housings.

Bismuth is also used as a catalyst or catalyst precursor in oxidation and condensation reactions within specialty chemical production for various industrial sectors.

In metallurgy, it acts as a lead replacement in free-machining alloys and low-melting fusible alloys used in safety devices and precision casting applications.

Bismuth is supplied as ingots, shots, granules, and high-purity pellets to suit different downstream processing requirements and specific manufacturing workflows.

Standard commercial grades range from technical purity to high-purity material for pharmaceutical and electronic applications where particle size control is critical.
