Antimony Lump

Product Overview

Antimony lump is a silvery-white metal with excellent physical and chemical properties, commonly used in the manufacture of various industrial alloys and other applications. Its relative density is 6.68, with a melting point of approximately 630°C and a boiling point of about 1635°C. It dissolves easily in aqua regia and concentrated sulfuric acid but is insoluble in water. Antimony is primarily found in nature in the form of stibnite (Sb₂S₃) and is an important mineral resource in China.

Key Features

• High Purity:Available in purities ranging from 4N to 6N, ensuring effective performance in industrial applications.
• Variety of Forms:Can be produced in various forms such as bars, lumps, and powders to meet different needs.
• Good Heat Resistance:Performs exceptionally well under high-temperature conditions, suitable for high-temperature applications.

Applications

• Industrial Alloys:Used in the battery industry for manufacturing battery grids and terminal components, and in mechanical and electrical transportation industries for producing bearing alloys, antimony bronze, and type metal.
• Flame Retardants:Antimony trioxide is an important raw material for flame retardants, widely applied in plastics, papermaking, textiles, and rubber preparation.
• Glass and Ceramics Industry:Adding small amounts of antimony enhances the strength and heat resistance of glass and serves as a stabilizer and thickening agent in ceramics.
• Semiconductors:Antimony lump can be used to produce specific types of semiconductor materials, such as indium antimonide, known for its high conductivity and good thermal stability.
• Other Applications:Used in the manufacture of pigments, catalysts, thermometers, and neutron sources.
