Description

Lithium7 Hydroxide is a specialized inorganic compound of significant interest in advanced material science and nuclear chemistry. Its unique isotopic composition makes it a critical precursor for high-performance applications where precise chemical and physical properties are required. This product is essential for researchers and manufacturers in the nuclear energy sector, specialty glass and ceramic production, and as a starting material for synthesizing other isotopically-enriched lithium compounds.

Application

• Nuclear Industry: Key material as a pH control agent and corrosion inhibitor in primary coolant systems of pressurized water reactors (PWRs).
• Specialty Ceramics & Glass: Used in the formulation of low-expansion, high-strength glasses and ceramics for optical and electronic components.
• Organic Synthesis: Acts as a strong, non-nucleophilic base in sensitive reactions where common bases like sodium or potassium hydroxide are unsuitable.
• Lithium Compound Synthesis: Serves as a primary precursor for the production of other isotopically-enriched lithium salts, such as Lithium-7 Carbonate or Lithium-7 Chloride.
• Electrolyte Additive: Employed in advanced battery research, particularly for next-generation lithium-ion and lithium-air battery systems to improve stability.
• Catalysis: Utilized as a catalyst or catalyst precursor in specific polymerization and organic transformation processes.

Quality Control

Our Lithium7 Hydroxide is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high isotopic purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (Li-7 atom %), chemical assay, and impurity profiles. We adhere to relevant nuclear-grade material specifications and good manufacturing practices.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., argon or nitrogen) to prevent moisture absorption and carbonation. Keep away from strong acids and incompatible materials.
