Antimony, a silvery-white, brittle metalloid, is sourced primarily from stibnite ore and combines metallic and non-metallic traits. This element, commonly used in various industries, plays crucial roles: serving as a hardening agent in lead alloys for batteries, cables, and ammunition and as a component in flame retardants, enhancing fire resistance in plastics and textiles. Additionally, it aids in removing bubbles from aluminum casting, while its historical medicinal applications have significantly diminished due to its toxic nature. Antimony’s presence extends to diverse sectors, including semiconductor manufacturing, pigments for paints, and catalysts in polyester production. Still, its toxicity necessitates cautious handling and disposal practices to prevent health and environmental risks.
