Description

Yttrium Nitrate Tetrahydrate is a high-purity inorganic salt of the rare earth element yttrium, serving as a critical precursor material in advanced manufacturing and research. Its primary value lies in providing a soluble and reactive source of yttrium ions for the synthesis of specialty materials, where precise composition and purity are paramount. This compound is essential for industries focused on phosphors, ceramics, catalysts, and specialized glass formulations, where it imparts unique optical and structural properties.

Application

• Phosphor Manufacturing: A key raw material for producing red phosphors used in cathode ray tubes (CRTs), fluorescent lamps, and LED components.
• Advanced Ceramics & Superconductors: Used in the synthesis of yttrium-stabilized zirconia (YSZ) for thermal barrier coatings, solid oxide fuel cells, and high-temperature superconductors like YBCO (Yttrium Barium Copper Oxide).
• Catalyst Preparation: Serves as a precursor for catalysts in petroleum refining, automotive exhaust systems, and organic synthesis reactions.
• Specialty Glass & Optics: Imparts high refractive index and stability to glasses used in lenses, lasers, and radiation-resistant windows.
• Chemical Vapor Deposition (CVD): A source material for depositing thin films of yttrium oxide or other yttrium-containing compounds on substrates.
• Research & Development: Employed in academic and industrial labs for developing new materials, studying catalytic processes, and exploring luminescent properties.

Quality Control

Our Yttrium Nitrate Tetrahydrate is produced under stringent quality management systems to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive quality assurance, with product specifications tailored to meet the demands of high-tech applications in electronics and materials science. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available for every batch upon request, supporting your quality and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere to minimize oxidation and caking.
