Niobium pentachloride Specification

The Niobium pentachloride, with the CAS registry number 10026-12-7, is also known as Niobium(V) chloride. It belongs to the product categories of Metal halide; Niobium Salts; Crystal Grade Inorganics; Materials Science; Metal and Ceramic Science; Niobium; Salts. Its EINECS number is 233-059-8. This chemical's molecular formula is Cl₅Nb and molecular weight is 270.17. What's more, its systematic name is niobium(+2) cation pentachloride. Its classification code is Mutation data. This chemical should be sealed and stored in a ventilated and dry place. Moreover, it should be protected from light. It hydrolyzes in air, and samples are often contaminated with small amounts of NbOCl₃. It is often used as a precursor to other compounds of niobium. This substance is the main precursor to the alkoxides of niobium, which find niche uses in sol-gel processing. It is also the precursor to many other laboratory reagents.

Preparation: Industrially, Niobium pentachloride is obtained by direct chlorination of niobium metal at 300 to 350 °C. In the laboratory, it is often prepared from Nb₂O₅, the main problem being incomplete reaction to give the oxyhalides. The conversion can be effected with thionyl chloride: It also can be prepared by chlorination of niobium pentoxide in the presence of carbon at 300°C. The products, however, contain small amounts of NbOCl₃.

2 Nb + 5 Cl₂ → 2 NbCl₅

When you are using this chemical, please be cautious about it as the following:
This chemical is harmful by inhalation, in contact with skin and if swallowed. It can cause burns. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. After contact with skin, you should wash immediately with plenty of ... (to be specified by the manufacturer). When using it, you need wear suitable protective clothing, gloves and eye/face protection. After using it, you must ake off immediately all contaminated clothing.
