Product Overview
Tungsten(VI) chloride (WCl₆) is a high-purity inorganic compound with a minimum assay of 99.9% on a trace metal basis, ensuring minimal impurities for critical applications. This volatile solid appears as a dark blue-black crystalline powder, highly hygroscopic and sensitive to moisture, requiring careful handling under inert conditions. Its strong Lewis acidity and ability to form coordination complexes make it a versatile reagent in advanced chemical synthesis, particularly as a precursor for tungsten-based catalysts and chemical vapor deposition (CVD) processes. The compound decomposes in water, releasing hydrogen chloride, and must be stored in airtight containers to prevent hydrolysis. Its high reactivity with organic solvents and metal substrates enables precise control in thin-film deposition and nanotechnology applications. The 99.9% purity grade guarantees consistent performance in research and industrial settings where trace metal contamination could compromise results. Compatible with anhydrous solvents like toluene or THF, this reagent is essential for producing tungsten carbides, nitrides, and other refractory materials. Proper storage under argon or nitrogen extends shelf life and maintains reactivity for long-term use.
FAQs
1. What is the shelf life of tungsten(vi) chloride when stored properly?
When stored in a tightly sealed container under dry, inert gas (argon/nitrogen) at room temperature, tungsten(vi) chloride remains stable for 24 months from the date of manufacture. Exposure to humidity significantly reduces its usability.
2. Can this compound be used directly in aqueous solutions?
No, tungsten(vi) chloride hydrolyzes rapidly in water, forming tungstic acid and hydrogen chloride. It must be handled in anhydrous conditions using dry solvents or inert atmospheres.
3. What are the key safety precautions for handling this product?
Always use in a fume hood with proper ventilation, as it releases corrosive HCl gas upon contact with moisture. Wear moisture-resistant gloves, safety goggles, and a lab coat. Avoid inhalation of dust or vapors.
4. Is this grade suitable for semiconductor fabrication?
The 99.9% trace metal basis purity makes it appropriate for many semiconductor applications, but additional purification may be required for ultra-high-purity thin-film deposition in advanced electronics.
5. How does the purity compare to standard industrial-grade tungsten(vi) chloride?
This 99.9% trace metal basis grade contains significantly fewer metallic impurities (typically <100 ppm) compared to industrial grades (95-98% purity), making it ideal for research and high-precision applications where contamination could affect outcomes.
