Overview
Antimony wire is a refined form of antimony metal, typically available in high purity (99.9% or higher). It is produced through processes like electrolysis or zone refining to remove impurities. Antimony wire is valued for its metallurgical and chemical properties, making it a critical material in specialized industries such as electronics and flame retardant manufacturing. Due to its brittle nature, antimony wire is often handled carefully during production and transportation. It is commonly supplied in coils or straight lengths, depending on the application requirements. The wire's silvery-white appearance and conductive properties make it distinguishable from other metal wires.
Physical and Chemical Properties
Antimony wire exhibits a density of 6.68 g/cm³ and melts at 630.63°C, with a boiling point of 1587°C. Unlike many metals, it is brittle and lacks ductility, which limits its use in applications requiring flexibility. The wire is insoluble in water but reacts with acids, forming antimony salts. Its electrical conductivity is moderate, making it suitable for certain semiconductor applications. Antimony wire is also resistant to corrosion under normal conditions, though prolonged exposure to moisture can lead to surface oxidation. These properties are carefully considered in industrial settings to ensure optimal performance.
Main Applications
Antimony wire is primarily used in the production of semiconductors, where it serves as a dopant to modify the electrical properties of silicon and germanium. It is also a key component in lead-antimony alloys, which are employed in batteries, bearings, and solder. Another significant application is in flame retardants, where antimony trioxide (derived from antimony wire) acts as a synergist with halogenated compounds. Additionally, the wire is used in specialized glass production and as a catalyst in certain chemical reactions. Its versatility across industries underscores its importance in advanced manufacturing.
Safety and Storage
Antimony wire poses health risks if inhaled or ingested, as antimony compounds are toxic. Workers handling the material should wear protective gloves, masks, and eyewear to minimize exposure. Proper ventilation is essential in areas where antimony dust or fumes may be present. Storage recommendations include keeping the wire in a dry, cool environment, away from oxidizers and acids. Containers should be tightly sealed to prevent moisture absorption and contamination. In case of spills, collect the material using non-sparking tools and dispose of it according to local hazardous waste regulations.
B2B Procurement Guide
When sourcing antimony wire, prioritize suppliers with certifications such as ISO 9001 to ensure quality consistency. Specify the required purity level (e.g., 99.9% or 99.99%) and inquire about testing methods like atomic absorption spectroscopy. Pricing varies based on purity, quantity, and market conditions, with typical ranges of $20-$50 per kg. For bulk orders, negotiate long-term contracts to secure stable pricing. Verify logistical capabilities, as antimony wire requires careful packaging to prevent breakage during transit. Establish clear communication channels for technical support and compliance documentation.
