Description

Tetrachloroniobium (CAS NO 56095-45-5) is a high-purity inorganic halide compound of niobium, serving as a critical precursor in advanced materials synthesis. Its primary value lies in its role as a versatile source of niobium for the deposition of thin films and the synthesis of specialty catalysts and ceramics. This product is essential for manufacturers and research institutions in the semiconductor, specialty chemical, and advanced ceramics industries seeking reliable, high-quality raw materials for their processes.

Application

• Chemical Vapor Deposition (CVD): A key precursor for depositing niobium-containing thin films, such as niobium nitride (NbN) or niobium carbide (NbC), used in superconducting devices and hard coatings.
• Catalyst Synthesis: Employed as a starting material for preparing niobium-based catalysts, including solid acid catalysts used in petrochemical refining and organic synthesis.
• Advanced Ceramics Production: Acts as a niobium source in the sol-gel or solid-state synthesis of high-performance ceramics like lithium niobate (LiNbO₃) for electro-optics.
• Organic Synthesis & Coordination Chemistry: Used as a Lewis acid catalyst or reagent in specialized organic transformations and for synthesizing niobium coordination complexes.
• Materials Research: A fundamental reagent in academic and industrial R&D for developing new niobium-based functional materials.

Quality Control

Our Tetrachloroniobium is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and impurity profile analysis via techniques such as titration and ICP-MS. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry, and well-ventilated area under an inert atmosphere (e.g., argon or nitrogen) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
