Description générale

Niobium(V) chloride is a yellow crystalline solid with a high melting point. It is widely used in the field of catalysis, semiconductor devices, and batteries. It is a highly specialized Lewis acid in chemical synthesis, activating alkenes for the carbonyl-ene reaction and the Diels-Alder process.

Application

[1]Niobium(V) chloride can be used:
  • As a precursor to prepare K2NbF7:Mn4+ red phosphors for white light-emitting diode(LED) devices.[2]
  • As a Lewis acid to synthesize fluorescein dye derivatives for dye-sensitized solar cells.[3]
  • As a dopant to enhance the thermoelectric properties of n-type tin selenide.[4]
  • As a precursor to synthesize Nb2O5 microspheres and TiNb2O7 nanoparticles as high-rate capability and long-cycle-life anode materials for lithium-ion batteries .[5]
Used to form mixed chloro-aryloxide compounds, such as [Nb(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.†

Questions

1–2 sur 2 questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 réponse
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
