General description

Iron (Fe) is a dense, malleable, andductile metal known for its strength and versatility. This product features agranular particle size of 10-40 mesh, a resistivity of 9.71 μΩ-cm at 20°C, anda density of 7.86 g/mL at 25 °C. Iron is widely utilized in various industrialapplications due to its excellent mechanical properties and abundance. Ourhigh-purity iron is characterized by an assay of >99.99% trace metals basis,ensuring exceptional quality and reliability for sensitive applications inelectronics, material science, and research. Heterogeneous Catalysts: Ironis used in various catalytic processes, including the Haber-Bosch process forammonia synthesis, where it serves as a catalyst.Batteries: Iron is used in some types of batteries, suchas iron-air batteries, which have potential for energy storage applications.

Application

  • Progress and perspectives on iron-based electrode materials for alkali metal-ion batteries: a critical review.: This review explores the recent advancements and future prospects of iron-based electrode materials in alkali metal-ion batteries, highlighting their potential for high energy density and sustainable energy storage solutions (Li et al., 2024).
  • Iron-Based Electrodes Meet Water-Based Preparation, Fluorine-Free Electrolyte and Binder: : This study examines the use of water-based preparation methods and fluorine-free electrolytes in the development of iron-based electrodes, proposing a more sustainable approach to lithium-ion battery production (Valvo et al., 2017).

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
