一般描述

六水硝酸铈(III)是硝酸铈最常见的形式。它是一种白色到黄色的结晶盐,极易溶于水、酒精和丙酮,尽管溶液看起来略微浑浊。像许多三价金属硝酸盐一样,六水硝酸铈(III)熔点仅为 57 °C,在低温下也能热分解,从 190 °C 开始,在 280 °C 时迅速分解,在 390-400 °C 时完全分解。

应用

六水硝酸铈 (III) 被广泛用作铈的来源,特别是在合成微纳米结构的氧化铈方面。六水硝酸铈 (III) 溶解度高,分解温度低,是水热反应、溶胶-凝胶处理、共沉淀和煅烧反应的理想试剂。

二氧化铈是研究得最为彻底的材料之一,是催化和固体氧化物燃料电池的平台。因此,科学家们已经开发出了控制良好的合成方案,使用六水硝酸铈 (III) 来制备包括纳米立方体、纳米管和纳米棒在内的氧化铈纳米颗粒。定制合成有利于使用二氧化铈作为催化剂载体,例如利用微观结构的孔隙来浸渍金属[1]和金属合金[2],或者合成基于二氧化铈的材料,如二氧化锆。[3]

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.
