Description

Scandium Nitrate CAS NO 16999-21-6 is an inorganic salt of scandium, a rare-earth element, valued for its unique chemical and physical properties. This compound serves as a critical precursor material for synthesizing high-performance ceramics, catalysts, and optical materials. It is essential for manufacturers and researchers in advanced electronics, solid oxide fuel cells, and high-intensity metal halide lighting.

Application

• Advanced Ceramics & Solid Electrolytes: A key precursor for producing scandium-stabilized zirconia (ScSZ), a vital material in solid oxide fuel cells (SOFCs) and oxygen sensors due to its high ionic conductivity.
• High-Intensity Lighting: Used in the manufacture of metal halide lamps, where scandium iodide, derived from the nitrate, produces a highly efficient, natural white light.
• Catalyst Synthesis: Employed in the preparation of catalysts for organic synthesis and petroleum refining, where scandium acts as a potent Lewis acid.
• Laser & Optical Materials: Serves as a starting material for growing single crystals (e.g., scandium garnets) used in solid-state lasers and other optical devices.
• Electronics & Semiconductors: Used in thin-film deposition processes to create scandium-containing films for next-generation electronic and spintronic devices.
• Research & Development: A fundamental reagent in academic and industrial R&D for exploring new materials, including superconductors and magnetic alloys.
• Aerospace Alloys: While primarily used as an oxide, its chemistry is foundational for developing scandium-aluminum master alloys that significantly strengthen and lighten aerospace components.

Quality Control

Our Scandium Nitrate is produced under stringent quality management systems. Each batch undergoes comprehensive analysis to ensure high purity and consistency, with traceability from raw material to final product. A Certificate of Analysis (COA) detailing assay, impurity profiles (including other rare earths and heavy metals), and physical parameters is provided with every shipment. We can support compliance with various industry standards upon request.

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 in a dry environment to prevent caking and hydrolysis. For long-term storage of high-purity grades, consideration should be given to storage under an inert atmosphere to minimize potential oxidation.
