Description

Yttrium Iodide CAS NO 13470-38-7 is an inorganic salt of the rare earth metal yttrium, widely utilized as a high-purity precursor in advanced material synthesis. Its primary commercial value lies in its role as a critical dopant and starting material for producing specialized phosphors and optical crystals. This compound is essential for manufacturers and R&D facilities in the electronics, lighting, and chemical vapor deposition (CVD) sectors seeking to develop next-generation luminescent and semiconductor materials.

Application

• Phosphor Manufacturing: A key dopant source for producing yttrium-based phosphors used in LEDs, display screens, and X-ray intensifying screens.
• Optical Crystal Growth: Serves as a starting material in the synthesis of single crystals for solid-state lasers and scintillation detectors.
• Chemical Vapor Deposition (CVD): Used as a volatile precursor for depositing thin films of yttrium-containing compounds in semiconductor and coating applications.
• Research & Development: Employed in academic and industrial labs for exploring new catalytic systems and advanced inorganic materials.
• Specialty Glass Production: Acts as an additive to modify the refractive index and other optical properties of technical glasses.
• Organic Synthesis Catalyst: Functions as a Lewis acid catalyst in specific organic transformations within fine chemical production.

Quality Control

Our Yttrium Iodide is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, trace metal impurities, and physical characteristics. Our quality systems are designed to meet the exacting standards of the electronics and advanced materials industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and degradation. Handle and store under an inert atmosphere (e.g., argon or nitrogen) for long-term stability.
