Modern purification processes provide ultra-high purity tungsten(VI) chloride, ensuring consistent and reliable performance in high-end applications such as semiconductors and optical coatings, and effectively reducing defects caused by impurities.
WCl6 is a strong Lewis acid, capable of efficiently catalyzing a variety of organic reactions, such as olefin polymerization and Friedel-Crafts alkylation.
Its high reactivity allows for milder reaction conditions and higher yields, making it extremely valuable in fine chemicals.
Compared to other tungsten chlorides, tungsten(VI) chloride exhibits suitable volatility and good thermal stability, enabling the preparation of high-purity, uniform tungsten and tungsten compound films.
In the chemical industry, tungsten(VI) chloride serves as a highly efficient catalyst or co-catalyst, participating in key reactions such as epoxidation and ring-opening polymerization to produce specialty polymers and high-value-added chemicals.
It can be used as a precursor for tungsten nanoparticles and tungsten oxide materials, and applied in optoelectronics and catalysis.
WCl6 can be used in the preparation of semiconductor, electrode materials, high-temperature resistant and corrosion-resistant thin films.
Tungsten(VI) chloride reacts with moisture and oxygen to release hydrogen chloride and tungsten oxide. It should be handled in an anhydrous, inert gas-protected environment.
It is recommended to store it in a sealed container under a nitrogen or argon atmosphere to avoid contact with air and moisture.
WCl6 itself and its hydrolysis products are highly corrosive and can burn the skin, eyes and respiratory tract. Appropriate personal protective equipment, including acid-resistant gloves, goggles and protective clothing, must be worn during operation and carried out in a high-efficiency fume hood.
If skin contact occurs, immediately remove contaminated clothing, rinse with plenty of water for at least 15 minutes, and seek immediate medical attention.
It is strictly forbidden to store it with water, strong oxidants, strong alkalis, or active metal powders.
1. How should WCl6 be handled and weighed to ensure safety and prevent its deterioration?
All operations must be performed in a glove box filled with high-purity argon or nitrogen. Before weighing, ensure the sample and weighing bottle are fully equilibrated with the environment. Use dry weighing tools, act quickly, and immediately reseal the container afterward to minimize its contact time with the inert atmosphere.
2. If my WCl6 sample turns yellow or white upon contact with air, is it still usable?
No. The change from dark gray-blue to yellow or white indicates severe hydrolysis, producing tungsten chloride or tungstic acid, completely negating its value as a high-purity precursor. This deteriorated product has lost its activity and is not recommended for any application requiring high purity.
3. Can you provide different purity levels?
Wolfa offers research-grade, industrial-grade, and custom-made specifications, and can provide COA and SDS upon request.
Wolfa professionally supplies Tungsten(Ⅵ) Chloride, supporting small-batch sampling and large-volume procurement needs. Packaging options include ordinary glass bottles, glass ampoules, metal ampoules, etc.
