Description

Tellurium122 CAS NO 14390-71-7 is a high-purity, isotopically enriched form of the metalloid element tellurium, specifically the isotope with mass number 122. This material is critical for advanced research and industrial applications where precise isotopic composition directly impacts material properties and experimental outcomes. It is essential for scientists and engineers in fields such as semiconductor doping, nuclear medicine, and fundamental physics research, where isotopic purity is a key performance parameter.

Application

• Semiconductor Research & Development: Used as a dopant or component in advanced semiconductor materials, including II-VI compounds like cadmium telluride (CdTe), where isotopic purity can influence thermal and electronic properties.
• Nuclear Medicine & Radiopharmaceuticals: Serves as a target material for the production of radioisotopes like Iodine-123, used in diagnostic imaging, or as a precursor in therapeutic agent development.
• Fundamental Physics Research: Employed in experiments studying neutrinoless double-beta decay and other rare nuclear processes due to the favorable nuclear properties of tellurium isotopes.
• Metallurgy & Alloy Development: Used in specialized alloys to improve machinability, corrosion resistance, and strength, particularly in lead and copper alloys for specific technical applications.
• Analytical Chemistry Standards: Acts as a certified reference material (CRM) or internal standard in mass spectrometry and other isotopic analysis techniques for calibration and quality control.
• Thermoelectric Materials: Investigated as a component in high-efficiency thermoelectric materials (e.g., bismuth telluride) for power generation and cooling devices.
