Used in pharmaceuticals for treating gastrointestinal disorders, particularly in formulations for stomach ulcers and diarrhea due to its antimicrobial and protective coating properties. Common in cosmetics, especially in pearlescent pigments for eye shadows and nail polishes, providing a shimmer effect. Employed in lead-free alloys for low-melting-point applications such as fire sprinkler systems and safety devices. Utilized in the production of bismuth-based catalysts for synthetic chemistry. Applied in radiation shielding due to its high density and low toxicity, making it suitable for medical and industrial protective equipment. Also found in ceramic glazes and pigments to create unique visual effects and improve finish quality.
