Description

Pentakis(Diethylamino)Niobium(V) is a highly reactive organometallic compound used as a volatile precursor in advanced material synthesis. This compound is critical for depositing ultra-pure niobium-containing films with precise stoichiometric control. It is primarily utilized by manufacturers in the semiconductor, optical coating, and specialty catalyst industries for applications demanding high-purity metal sources.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): As a volatile precursor for depositing niobium nitride (NbN), niobium oxide (Nb2O5), and other niobium-based thin films on substrates.
• Semiconductor Manufacturing: For creating diffusion barriers, gate electrodes, or capacitor dielectrics in advanced microelectronic devices.
• Optical and Protective Coatings: Production of high-refractive-index layers for anti-reflective coatings, optical filters, and wear-resistant surfaces.
• Specialty Catalysis: Serving as a catalyst precursor or ligand in organic synthesis and polymerization reactions.
• Research & Development: Used in academic and industrial labs for developing new niobium-based materials, including superconductors and metal-organic frameworks (MOFs).
• Sol-Gel Processing: As a molecular precursor for synthesizing niobium oxide gels and nanoparticles.

Quality Control

Our Pentakis(Diethylamino)Niobium(V) is produced and handled under stringent conditions to ensure batch-to-batch consistency and high purity, essential for sensitive deposition processes. Quality is verified through advanced analytical techniques including NMR, FT-IR, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic nature, this material must be stored under a dry, inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C. Handle and open containers only in a certified glovebox or under strictly anhydrous conditions to prevent decomposition.
