Tantalum(V) chloride is an excellent water soluble crystalline Tantalum source for uses compatible with chlorides. Chloride compounds can conduct electricity when fused or dissolved in water. Chloride materials can be decomposed by electrolysis to chlorine gas and the metal. They can form either inorganic or organic compounds. TaCl5 is used in the preparation of catalyst for the polycyclotrimerizations of alkenediynes, chloro-aryloxide compounds and for the plasma-enhanced atomic layer deposition of tantalum nitride films. This product is involved in the preparation of tantalum(V) oxychloride. It is electrophilic and behaves like a Friedel-Crafts type catalyst.
Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing Tantalum(V) chloride contact us at sales@ereztech.com
