Used as a pigment in cosmetics and ceramics due to its pearlescent luster and chemical stability.

Also employed in radiation shielding materials because of bismuth's high atomic number, offering an environmentally friendly alternative to lead-based compounds.

In medicine, it serves as an intermediate in the synthesis of bismuth-containing pharmaceuticals with antimicrobial and gastroprotective properties.

Additionally, investigated for use in solid-state electrolytes for lithium-ion batteries owing to its ionic conductivity and thermal stability.
