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 over-the-counter medicines like those for upset stomach. Found in cosmetics, especially in pearlescent pigments for eye shadows and nail polishes, providing a shimmer effect due to its refractive properties. Used as a lead replacement in alloys for plumbing, bearings, and soldering materials because it is non-toxic and has a low melting point. Applied in the production of thermoelectric materials and fire detection devices due to its unique thermal and electrical characteristics. Used in radiation shielding, especially in medical applications, as it offers good attenuation of X-rays and gamma rays without the toxicity of lead.
