Description

Gd 7 CAS NO 556-75-2 is a high-purity gadolinium-based compound, specifically gadolinium(III) chloride, serving as a critical precursor in advanced material synthesis. This material is essential for producing specialty inorganic compounds and functional materials where precise control over gadolinium content is paramount. It is primarily utilized by manufacturers and research institutions in the fields of phosphors, specialty glass, catalysis, and advanced ceramic materials.

Application

• Phosphor Manufacturing: A key raw material for producing gadolinium-activated phosphors used in lighting, displays, and X-ray intensifying screens.
• Specialty Glass & Ceramics: Acts as a dopant to modify the optical and thermal properties of glasses and advanced ceramic composites.
• Catalysis Research: Serves as a precursor or catalyst component in organic synthesis and polymerization reactions.
• Magnetic Resonance Imaging (MRI) Research: Used in the development and study of contrast agent precursors and related diagnostic materials.
• Solid-State Chemistry: A fundamental starting material for synthesizing other gadolinium salts and complex inorganic compounds.
• Nuclear Applications: Employed in research related to neutron absorption and shielding materials due to gadolinium's high neutron capture cross-section.

Quality Control

Our Gd 7 is produced under stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical testing, including assay and trace metal analysis, to meet the exacting requirements of advanced material applications. A Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored in a cool, dry place, ideally under an inert atmosphere or in a desiccator to prevent hydrolysis. Recommended long-term storage temperature is 15-25°C.
