Description

Tungsten Hexakis(2-Ethylhexanolate) is a metal-organic compound (metal alkoxide) of tungsten. This compound serves as a high-purity, soluble precursor for depositing tungsten or tungsten oxide films in advanced materials synthesis. It is primarily utilized by manufacturers and R&D facilities in the electronics, catalysis, and specialty glass industries seeking precise control over material properties.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): As a volatile precursor for depositing tungsten metal or tungsten oxide thin films on semiconductors and optical components.
• Catalyst Synthesis: As a starting material for preparing homogeneous and heterogeneous tungsten-based catalysts for olefin metathesis, epoxidation, and other organic transformations.
• Sol-Gel Processing: For the production of high-purity tungsten oxide (WO3) nanoparticles, coatings, and electrochromic materials.
• Polymer & Composite Modification: As an additive or cross-linking agent to impart thermal stability, flame retardancy, or specific catalytic activity to polymers.
• Specialty Glass & Ceramics: As a doping agent to modify the electrical, optical, or thermal properties of glass and ceramic matrices.
• Research & Development: Serving as a key reagent in academic and industrial labs for exploring new tungsten-containing materials and catalytic processes.

Quality Control

Our Tungsten Hexakis(2-Ethylhexanolate) is produced under controlled conditions to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes rigorous analytical testing, including assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results for purity, metal content, and solvent residues is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool (15-25°C), dry, and well-ventilated area, away from incompatible materials. This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept sealed and purged after each use to maintain product integrity.
