Description générale

Calcium is a highly reactive and non-toxic metal often prepared by the aluminothermal or electrolysis methods. Calcium metal granules with a purity of 99% are a valuable material used in several industrial and academic applications. The granules are made from high-quality calcium and are produced under strict manufacturing standards to ensure their purity and quality. The granular form allows for easier handling and storage than a powder, making it convenient for use in various applications.

Application

Our 99% pure calcium metal granules are widely used as a reducing agent in the manufacturing of various metals, including uranium and thorium. They are also an essential component in the production of aluminum alloys that are commonly used in the aerospace and automotive industries. These calcium metal granules are also used in the desulfurization of steel and as a deoxidizer in the production of various metals. Furthermore, our calcium metal granules are extensively used in organic synthesis to reduce various functional groups, such as aldehydes, ketones, esters, and nitriles, to their corresponding alcohols. The metal is also utilized in the preparation of Grignard reagents, which serve as crucial intermediates in organic synthesis.
Precursor to Ca8Al3 and Ca13Al14; intermetallics with new metallic Zintl phases.7

Caractéristiques et avantages

  • Quality assured - made from high-quality raw materials and produced under strict manufacturing standards to ensure consistent performance.
  • Easier to handle and store - in comparison to powder, the granular form ensures higher stability during storage and handling of materials.

Questions

1–3 of 3 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.
      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
