Antimony

Antimony is a metallic chemical element with the symbol Sb (from Latin stibium) and atomic number 51. This silvery-white metalloid belongs to the nitrogen group in the periodic table and has a molecular weight of 121.76 g/mol. Antimony exhibits both metallic and non-metallic properties, making it a valuable material in various industrial applications. It occurs naturally in the Earth's crust and has been used by humans for thousands of years.

Antimony is a lustrous, silvery-white solid at room temperature with a brittle, crystalline structure. It has a melting point of 630.6°C and a boiling point of 1587°C. Antimony is poorly soluble in water but can dissolve in certain acids. It exhibits poor electrical and thermal conductivity compared to true metals. The element is stable in air at room temperature but can oxidize when heated, forming antimony oxides.

Antimony is primarily used as a flame retardant in plastics, textiles, and rubber products, often in the form of antimony trioxide. It serves as a hardening agent in lead alloys for batteries, bullets, and cable sheathing. The semiconductor industry uses high-purity antimony in infrared detectors and diodes. Other applications include glass manufacturing for decolorization, ceramics, and as a catalyst in polyester production. Traditional uses include pewter alloys and medicinal compounds.

Antimony should be handled with appropriate personal protective equipment including safety goggles, dust masks, and protective clothing to prevent inhalation and skin contact. Work in well-ventilated areas or use local exhaust ventilation to control dust exposure. Avoid generating dust during handling and use proper industrial hygiene practices. Wash hands thoroughly after handling and avoid eating, drinking, or smoking in work areas. Regular health monitoring may be recommended for workers with occupational exposure.

Antimony should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly closed and protect from moisture to prevent oxidation. Store away from strong acids, strong oxidizing agents, and halogenated compounds. Use appropriate containment to prevent environmental release. Ensure storage areas have adequate fire protection measures and maintain proper inventory management. Follow local regulations for storage of metallic substances.

Antimony exposure requires immediate attention depending on the route of contact. For skin contact, wash thoroughly with soap and water and remove contaminated clothing. If inhaled, move to fresh air immediately and seek medical attention if respiratory symptoms develop. For eye contact, flush with clean water for at least 15 minutes and seek medical evaluation. If ingested, do not induce vomiting and seek immediate medical attention. Always consult poison control centers or medical professionals for exposure incidents.

Antimony disposal must comply with local, national, and international waste regulations as it may be classified as hazardous waste. Contact authorized waste management companies specializing in metallic waste disposal. Avoid releasing antimony into the environment, including sewers, soil, or waterways. Recover and recycle when possible through specialized metal recovery facilities. Maintain proper documentation for waste tracking and disposal. Consult with environmental authorities for specific disposal requirements in your jurisdiction.

Antimony is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. Use appropriate packaging that meets UN specification requirements for Class 6.1 materials. Ensure proper labeling and documentation including transport documents and emergency response information. Vehicles must comply with ADR requirements for toxic substance transport. Drivers should have appropriate training and certification for transporting hazardous materials. Follow routing restrictions and emergency procedures as specified in transport regulations.

Antimony is regulated under various European and international frameworks including REACH regulation for chemical registration and evaluation. While not currently listed as a Substance of Very High Concern (SVHC), it may be subject to occupational exposure limits and health surveillance requirements. Some antimony compounds face restrictions in consumer products. Industrial users must comply with workplace safety regulations and environmental protection measures. Always verify current regulatory status as requirements may change over time.
