一般描述

Silicon carbide (SiC), also known as carborundum, is composed of silicon and carbon, forming a hard refractory ceramic material that exhibits extreme mechanical and thermal stability. This product is a SiC nanopowder with a particle size less than 100 nm and a high surface area of 70-90 m2/g. Our product is primarily made of the beta phase with approximately 3-15% adopting an amorphous structure. With a Mohs scale hardness of 9.5, silicon carbide is one of the hardest materials, which make its nanopowder useful in the production of abrasives for polishing and grinding and as a coating or composite material for high wear-resistance. SiC nanoparticles are also under research as sensors and imaging nanoprobes for bioscience and clinical diagnosis.

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  5. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  6. I am interested in other types of nanoparticles. What does Sigma-Aldrich offer for my application?

    Sigma-Aldrich offers a variety of nanoparticles (both as powders and as dispersions), organized in the Online Product Catalog by element.

  7. Does Silicon carbide, Product 594911, have any surface modification?

    According to the supplier, the surface of these silicon carbide nanoparticles are not modified in any way. The material consists solely of silicon and carbon.

  8. How is Silicon carbide, Product 594911, synthesized?

    Conventionally, silicon carbide is prepared using the Acheson process. Specifically, the supplier of these silicon carbide nanoparticles considers the method of manufacturing proprietary.

  9. My question is not addressed here, how can I contact Technical Service for assistance?
