Overview
Antimony granules are a purified metallic form of antimony (Sb), a lustrous gray metalloid. They are produced by refining stibnite ore or through electrolysis. Due to their brittleness and low thermal conductivity, antimony granules are rarely used alone but serve as a critical additive in alloys and industrial compounds. In B2B markets, antimony granules are traded primarily for their role in enhancing material properties, such as hardness in lead alloys for batteries or flame resistance in plastics. Global supply is concentrated in China, Bolivia, and Russia, with pricing influenced by geopolitical factors and environmental regulations.
Physical and Chemical Properties
Antimony granules exhibit a distinctive silvery-white appearance but tarnish to a bluish hue when exposed to air. Their brittle nature makes mechanical processing challenging without alloying. Chemically, antimony is stable at room temperature but reacts with halogens and strong acids. Notably, antimony’s flame-retardant properties stem from its ability to release halogen radicals when heated, which interrupt combustion chains. This property is leveraged in plastics, textiles, and electronics. The granules’ insolubility in water minimizes environmental mobility, though their toxicity necessitates careful handling.
Main Applications
The primary use of antimony granules is in lead-antimony alloys for lead-acid batteries, where they improve grid strength and charge efficiency. They are also a key component in flame retardants, accounting for ~60% of global consumption, especially in plastics for electronics and construction. In semiconductor manufacturing, high-purity antimony (99.99%) is doped into silicon for N-type semiconductors. Lesser applications include pewter production, ammunition hardening, and glass decolorization. Emerging uses in lithium-ion battery anodes are under research but not yet commercialized.
Safety and Storage
Antimony granules pose health risks if inhaled as dust or ingested, causing respiratory irritation, gastrointestinal distress, or chronic toxicity. OSHA recommends a permissible exposure limit (PEL) of 0.5 mg/m³ for antimony dust. Storage requires airtight containers in dry, ventilated areas, separated from oxidizers (e.g., nitrates) and acids to prevent hazardous reactions. Spills should be collected using non-sparking tools and disposed of as hazardous waste. Suppliers must provide SDS (Safety Data Sheets) complying with GHS standards.
B2B Procurement Guide
When sourcing antimony granules, prioritize suppliers with ISO 9001 certification and traceable refining processes. Specify purity (industrial-grade: 99.6%, high-purity: 99.9%) and particle size (typically 1–10 mm). Packaging options include 25-kg drums or 1-ton bulk bags. Due to price volatility, consider long-term contracts with price adjustment clauses. Logistics should avoid humid routes to prevent oxidation. Chinese suppliers dominate the market, but alternative sources in Tajikistan or Australia may offer competitive tariffs.
