Description

Niobiumchloride, also known as Niobium(V) chloride, is a high-purity inorganic compound essential for advanced material synthesis and catalysis. Its primary value lies in its role as a versatile precursor for depositing niobium-containing films and synthesizing niobium-based organometallic complexes. This material is critical for manufacturers and R&D facilities in the semiconductor, specialty chemical, and advanced ceramics industries seeking reliable, high-quality inorganic reagents.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): A key precursor for depositing niobium nitride (NbN), niobium carbide (NbC), and niobium oxide (Nb2O5) thin films used in superconducting devices, hard coatings, and optical layers.
• Catalyst Synthesis: Serves as a starting material for preparing Ziegler-Natta and other olefin polymerization catalysts, as well as catalysts for organic synthesis and petrochemical processes.
• Production of Niobium Metal: Used in the reduction process via the Kroll or other metallothermic methods to produce high-purity niobium metal.
• Specialty Glass & Ceramics: Imparts high refractive index and other specific optical/mechanical properties to advanced glass and ceramic formulations.
• Research & Development: A fundamental reagent in inorganic and materials chemistry research for exploring new niobium compounds and their properties.
• Organic Synthesis: Acts as a Lewis acid catalyst in specialized organic reactions, such as Friedel-Crafts acylations and chlorinations.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this product must be stored in a cool, dry place under an inert atmosphere (e.g., argon or nitrogen) to prevent hydrolysis and degradation. Recommended storage temperature is 2-25°C. Keep the container tightly sealed in a dry and well-ventilated area, away from incompatible materials such as strong bases and active metals.
