Antimony (Sb) is a brittle metalloid with a silvery-white appearance, classified as a semimetal that exhibits both metallic and nonmetallic properties. It is primarily used as a hardening agent in lead-based alloys, a flame retardant additive in polymers and textiles, and a dopant in semiconductor applications. Engineers select antimony for battery plates, bearings, and cable sheathing where hardness and brittleness are advantageous, and for flame-retardant compounds in applications requiring improved fire safety without halogenated additives.
