General description

Aluminum Nitride(AlN) is a non-oxide semiconductor material with a hexagonal Wurtzite crystal structure. It has a wide direct bandgap of 6.12 eV.[1] AIN is a suitable additive in making thermal grease and electric cable insulation owing to its very high thermal conductivity (300 W/(m. K)) and electrical resistivity.[2] It is also used in microelectronics, electroluminescent devices, and sensors because of its non-toxicity, superior thermal, electrical, mechanical, and chemical properties.[3]

Application

Aluminum Nitride can be used as a:
  • ceramic material in the preparation of nano capsulated phase change material for building thermal management systems.[4]
  • matrix in the preparation of metacomposites along with graphene platelets to improve their thermal conductive properties.[5]
  • foaming agent in the preparation of foam glass using glass waste.[6]
It is also used to prepare ceramic matrix composite material along with molybdenum to generate high-energy X-rays.[7]

Questions

1–3 of 3 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

  3. I would like to ask about the shape of ALN powder.

    1 answer

    1. The bulk of this material is hexagonal by x-ray deffraction. This is qualitative data only and not a product specification.
