Description

Thulium Nitrate is an inorganic salt of the rare earth element thulium, widely used as a specialized precursor in advanced materials and research. Its high purity is critical for ensuring consistent performance in optical and electronic applications where trace impurities can significantly alter properties. This compound is essential for manufacturers and researchers in the fields of specialty glass, phosphors, and chemical vapor deposition. Thulium Nitrate CAS NO 14985-19-4 is supplied with detailed technical data to meet the stringent requirements of high-tech industries.

Application

• Phosphor and Laser Material Production: Serves as a key dopant for creating upconversion phosphors and solid-state laser crystals that emit in specific infrared and visible wavelengths.
• Specialty Glass and Optical Fibers: Used to manufacture glasses with unique refractive indices and for doping optical fibers to create active gain media in amplifiers.
• Chemical Vapor Deposition (CVD): Acts as a high-purity precursor for depositing thulium-containing thin films in semiconductor and coating applications.
• Research & Development: A fundamental starting material in academic and industrial laboratories for synthesizing novel thulium-based compounds and catalysts.
• Catalysis: Employed in specialized organic synthesis and polymerization reactions where rare earth elements act as catalysts.
• Nuclear Applications: Utilized in certain radiation-related research and development contexts due to thulium's isotopic properties.

Quality Control

Our Thulium Nitrate is produced and handled under a strict quality management system. Each batch undergoes comprehensive analysis to verify key parameters such as purity, rare earth content, and impurity profiles against established specifications. Certificates of Analysis (COA) documenting these results are provided to ensure full traceability and compliance with your project requirements. We support custom purity grades, including high-purity (99.9%, 99.99%, and 99.999% / 3N, 4N, 5N) specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and decomposition. For long-term storage, consider the use of a desiccator.
