一般說明

仲丁醇铝是一种金属有机化学气相沉积前驱体和螯合剂。它被广泛用作溶胶-凝胶前驱体,通过原子层沉积法沉积氧化铝薄膜。

應用

仲丁醇铝可用作前驱体:
  • 制备用于锂金属负极的Al2O3基准固态电解质。这可确保循环寿命长、恒定电流密度高。
  • 采用低温溶胶-凝胶法合成纳米尖晶石MgAl2O4粉末。
  • 制备透明的超疏水氧化铝薄膜,防止弄脏太阳能电池板。
  • 合成大表面积介孔氧化铝,制造Li-S电池隔膜涂层的功能夹层。它有助于抑制穿梭效应,提高循环稳定性和倍率性能。

特點和優勢

  • 适用于薄膜沉积
  • 在各种溶剂中均可溶,可轻松制备溶液基前驱体
  • 热稳定性高
  • 促进催化金属纳米颗粒锚定到基材上

已用于制备高表面积氧化铝,其中以 2,4-戊二酮(Aldrich 产品 P775-4)作为螯合剂。

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
