Description

Gadolinium(III) Sulfate 99.99+% is a high-purity inorganic salt of the rare earth element gadolinium. This ultra-high purity grade is critical for applications demanding exceptional material consistency and minimal metallic impurities. It is primarily utilized in advanced material science, specialized chemical synthesis, and high-tech research and development. The product is supplied as a hygroscopic powder, requiring careful handling and storage to maintain its specified quality.

Application

• Phosphor and Luminescent Material Precursor: A key starting material in the synthesis of gadolinium-based phosphors for displays, lighting, and X-ray intensifying screens.
• Specialty Catalyst and Reagent: Employed in organic synthesis and catalytic processes where gadolinium ions act as Lewis acids or promoters.
• Research & Development (R&D): Used in academic and industrial laboratories for developing new materials, studying magnetic properties, and exploring novel chemical applications of rare earth compounds.
• Dopant for Optical Glasses and Crystals: Serves as a doping agent to modify the refractive index, density, and radiation resistance of specialty glasses and single crystals.
• Magnetic Resonance Imaging (MRI) Research: Investigated for potential use in developing novel contrast agents due to gadolinium's paramagnetic properties.
• High-Purity Chemical Manufacturing: Acts as an intermediate for producing other ultra-high purity gadolinium salts and compounds.

Quality Control

Our Gadolinium(III) Sulfate 99.99+% is manufactured under controlled conditions to ensure batch-to-batch consistency and meets stringent purity specifications. Quality is verified through advanced analytical techniques including Inductively Coupled Plasma (ICP) and titration methods. A Certificate of Analysis (COA) detailing purity, assay, and trace metal content is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C) under low humidity conditions. For long-term storage, consider the use of a desiccator or inert atmosphere to prevent moisture absorption and caking.
