Description

Antimony CAS NO 7440-36-0 is a lustrous, silvery-white metalloid element known for its hardness and brittleness. It is a critical industrial material valued for its ability to impart flame retardancy and hardness to various alloys. This product is essential for manufacturers in the flame retardant, lead-acid battery, semiconductor, and chemical catalyst industries seeking reliable and high-purity material.

Application

• Flame Retardants: A key synergist in halogenated flame retardants for plastics, textiles, rubber, and electronics, enhancing fire safety standards.
• Lead-Acid Batteries: Used as an alloying agent in lead plates to improve hardness, mechanical strength, and corrosion resistance.
• Alloy Hardener: Imparts increased hardness and strength to lead, tin, and copper-based alloys (e.g., pewter, bearing metals, solder).
• Semiconductors: Employed in the production of infrared detectors, diodes, and other devices utilizing compounds like indium antimonide (InSb).
• Chemical Catalysts: Serves as a catalyst, notably in the production of polyethylene terephthalate (PET) plastic.
• Ceramics & Glass: Acts as a fining agent to remove bubbles from glass and as an opacifier in ceramics and enamels.
• Military & Ammunition: Used in tracer bullets, primers, and other pyrotechnic compositions.

Quality Control

Our Antimony is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and compliance with industry specifications. We provide comprehensive Certificates of Analysis (COA) detailing purity, metallic impurities, and physical properties. Our quality commitment supports applications requiring high material integrity, from industrial alloys to specialized chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, strong oxidizers, and halogens. For long-term storage, maintaining conditions at room temperature (15-25°C) in a low-humidity environment is recommended to prevent surface oxidation.
