CAS 7721-01-9 Tantalum(V) Chloride Powder TaCl5 used in the preparation of tantalum

Brief Description of  Tantalum(V) Chloride Powder TaCl5
Tantalum(V) chloride, also known as tantalum pentachloride, is an inorganic compound with the formula TaCl5.
It takes the form of a white powder and is commonly used as a starting material in tatalum chemistry.
It readily hydrolyzes to form tantalum(V) oxychloride (TaOCl3) and eventually tantalum pentoxide  (Ta2O5); this requires that it be synthesised and manipulated under anhydrous conditions, using air-free techniques.

Chemical Composition(%)





















Application of Tantalum(V) Chloride Powder TaCl5
1. Used as chlorinated compounds of organic compounds, chemical intermediates.
2. Used in the preparation of tantalum
Properties of  Tantalum(V) Chloride Powder TaCl5
The solubility of tantalum pentachloride increases to a slightly for the following series of aromatic hydrocarbons: benzene< toluene< m-xylene< mesitylene, as reflected in the deepening of colour of the solutions from pale yellow to orange.
Tantalum pentachloride is less soluble in cyclohexane and carbon tetrachloride than in the aromatic hydrocarbons.
Such solutions of tantalum pentachloride are also known to be poor conductors of electricity, indicating little ionization.
TaCl5 is purified by sublimation to give white needles.
