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.

General description
Application
Cerdioxid ist eine der am besten untersuchten Materialplattformen für die Katalyse und Festoxidbrennstoffzellen. Folglich entwickelten Wissenschaftler gut kontrollierte synthetische Protokolle mit Cer(III)-nitrat-hexahydrat zum Herstellen von Cerdioxid-Nanopartikeln, einschließlich Nano Cubes, Nanoröhrchen und Nanodrähte. Die anpassbare Synthese ermöglicht die Verwendung von Cerdioxid als Katalysatorträger, zum Beispiel zum Nutzen der Porosität der Mikrostruktur, um Metalle und Metalllegierungen zu imprägnieren, oder um beispielsweise Materialien auf Cerdioxid-Basis wie Cerdioxid-Zirkoniumdioxid zu synthetisieren.

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