詳細

炭化ケイ素（SiC）は別名カーボランダムとも呼ばれ、ケイ素と炭素で構成される硬質耐火セラミック材料で、極めて優れた機械的および熱的安定性を示します。本製品は、粒径 100 nm 未満、比表面積 70 ～ 90 m2/g の SiC ナノパウダーです。当社の製品は主にβ相で構成されており、約 3 ～ 15 % が非晶質構造となっています。 モース硬度 9.5 の炭化ケイ素は最も硬い材料のひとつであり、そのナノパウダーは研磨や研削用の研磨剤の製造や、耐摩耗性の高いコーティングや複合材料として有用です。SiC ナノ粒子は、バイオサイエンスや臨床診断用のセンサーやイメージングナノプローブとしても研究されています。

A simple and scalable synthetic strategy was developed for the fabrication of one-dimensional SiC nanostructures-nanorods and nanowires. Thin sheets of single-walled carbon nanotubes (SWNTs) were prepared by vacuum filtration and were washed repeatedly with sodium silicate (Na2SiO3) solution. The resulting

Silicon carbide (SiC) has unique chemical, physical, and mechanical properties. A factor strongly limiting SiC-based technologies is the high-temperature synthesis. In this work, we provide unprecedented experimental and theoretical evidence of 3C-SiC epitaxy on silicon at room temperature by using

質問

1–7/7 質問  

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

    1 回答

    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 回答

    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

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

    1 回答

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

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

    1 回答

    1. 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.

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

    1 回答

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

      役に立ちましたか？

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

    1 回答

    1. 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.
