Description

Tungsten(VI) Chloride (CAS NO 13283-01-7) is a high-purity, dark blue to black crystalline inorganic compound that serves as a crucial precursor in advanced materials synthesis. Its primary value lies in its role as a versatile source of tungsten in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes, enabling the creation of thin films and coatings with exceptional properties. This material is essential for manufacturers and R&D facilities in the semiconductor, electronics, and specialty chemical industries seeking to develop next-generation components and catalysts.

Application

• Semiconductor Manufacturing: As a key precursor for depositing tungsten-containing thin films, tungsten silicide (WSix), and diffusion barriers via CVD and ALD techniques.
• Catalyst Synthesis: Serves as a starting material for preparing homogeneous and heterogeneous catalysts used in petrochemical refining and organic synthesis.
• Surface Coating: Used to create wear-resistant and corrosion-resistant tungsten carbide (WC) coatings on industrial tools and components.
• Chemical Research: Acts as a fundamental reagent in inorganic and organometallic chemistry for synthesizing novel tungsten complexes.
• Optical Materials: Employed in the development of specialized glasses and ceramics with tailored refractive indices and durability.
• Nanomaterial Production: A vital precursor for the synthesis of tungsten oxide nanowires, nanotubes, and other nanostructures for sensing and energy applications.

Quality Control

Our Tungsten(VI) Chloride is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling via ICP-MS, and physical characterization. A detailed Certificate of Analysis (COA) documenting purity, metallic impurities, and physical specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (e.g., argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended long-term storage temperature is 2-8°C. Keep away from strong acids and organic solvents.
