Description

Antimony121 CAS NO 14265-72-6 is a high-purity antimony compound, specifically antimony-121, an isotope of the metalloid element antimony. This material is critical for applications requiring precise isotopic composition and high chemical purity, where standard elemental antimony is insufficient. It is primarily utilized in advanced research, semiconductor doping, and specialized alloy development within the electronics, nuclear, and metallurgical industries.

Application

• Semiconductor Manufacturing: Used as a precise dopant in the production of silicon and germanium-based semiconductors to modify electrical properties.
• Nuclear Industry: Serves as a component in radiation detection devices and shielding materials due to its specific nuclear properties.
• Specialized Metallurgy: Employed in the formulation of high-performance alloys, including lead-antimony types for batteries and solder, where isotopic consistency is key.
• Research & Development: Essential as a standard or tracer in geochemical, environmental, and materials science research.
• Catalyst Production: Acts as a component in catalysts for specific petrochemical and polymerization reactions.
• Flame Retardant Synergist: Used in combination with halogenated compounds to enhance flame retardancy in plastics and textiles for high-specification applications.
