General description

Tellurium is anon-radioactive and heaviest member of the chalcogen family. It has a widerange of oxidation states, from -2 to +6. It is widely used in the fields ofmetallurgy and electronics.

Application

Tellurium can be used as a precursor to prepare:
  • Tellurium-based nanomaterials for semiconductor application, such as CdTe nanoparticles via solvothermal synthesis.
  • Quantum dot solutions for fluorometric determination of bioactive compounds.
  • Thermoelectricmaterials, such as Cu4Mn2Te4 by the melting-quenching-SPS method.
Tellurium, in combination with potassium hydroxide, mediates the quantitative pinacolization of aromatic carbonyl compounds.[1]

Questions

1–2 of 2 Questions  

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

    1 answer

    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

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

    1 answer

    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.
