General description

Granular lithium is a form of lithium metal that has been ground into small granules. Lithium is a soft, silver-white metal that is highly reactive and flammable. Lithium has a low density of 0.534 g/cm3, which makes it one of the lightest metals. Like the other alkali metals, lithium has a low melting point (180 °C) and is a good conductor of electricity and heat. Granular lithium is highly reactive and behaves as a strong reducing agent. It must be handled with caution due to its potential to ignite or explode. Lithium reacts readily with water and oxygen to form lithium hydroxide and lithium oxide, respectively, and even reacts with nitrogen gas at room temperature, forming lithium nitride. Typically, lithium is stored in an argon glovebox and airtight containers to prevent exposure to moisture, air, and nitrogen. To make granular lithium, the metal is first extracted from ores such as spodumene or lepidolite using a process called lithium carbonate conversion. After the lithium has been purified to a high degree of purity, it is milled into granules by rotating blades.
Lithium is a low-density alkali metal that is widely used as an anode material in rechargeable and non-rechargeable batteries. It is also used to alloy with aluminum and magnesium to make them stronger and lighter.

Application

Lithium can be used as:
  • A precursor to synthesize Li-based alloys such as LiAl and LiSi alloys, which are applicable as anode materials in the field of energy conversion and storage.[1]
  • A reducing agent in the reduction of zirconium oxide compounds in molten LiCl salt.[2]
  • As starting material to synthesize a reducing agent(1,4-bis(trimethylgermyl)-1.4-dihydropyrazine), for the fabrication of nickel metal films.[3]

Questions

1–5 of 5 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  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
