The particle size or mesh size of this material is not determined on a lot-to-lot basis. However, historical data indicates particle size ranges as follows:
150µm/100 mesh - 212µm/70 mesh = 10%
45µm/325 mesh -150µm/100 mesh = 65-85%
<45µm/<325-400 mesh = 5-25%

Allgemeine Beschreibung
Reduced iron powder, also known as iron sponge, is a fine powdered form of iron that is commonly used in chemical synthesis processes. It is produced by the reduction of iron oxide in a controlled environment, typically through the use of hydrogen or carbon monoxide gas.
In chemical synthesis, reduced iron powder can be employed as a reducing agent, catalyst, or precursor in a wide range of reactions. It is commonly used to convert organic functional groups, such as aldehydes, ketones, and nitro compounds, into their corresponding reduced forms. It is also known to facilitate hydrogenation reactions.
Reduced iron powder finds applications in the production of iron-based catalysts, magnetic materials, pigments, and metal alloys. It is commonly used in pharmaceutical synthesis, organic chemistry, and industrial manufacturing. It is important to handle reduced iron powder with care due to its potential reactivity with moisture and oxygen, which may cause oxidation and result in changes to its properties. Proper storage and handling procedures should be followed to maintain its quality and prevent unwanted reactions.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
