Questions

1–9 of 9 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. What applications can Product 378097, Silicon carbide, be used for?

    1 answer
    1. Silicon carbide (SiC) has found use in a variety of commercial applications. Historically, SiC has been used most frequently in the metallurical, abrasive, and refactory industries. More recently, this material has found increased use in high technology applications (e.g. electronics, aerospace, automotive, etc.).

  4. What solvents can I use to dissolve Product 378097, Silicon carbide ?

    1 answer
    1. Unfortunately, Sigma-Aldrich does not test the solubility of this material. Fundamentally, Silicon carbide (SiC) is insoluble in water. However, according to Lange's Handbook of Chemistry (16th ed.), beta-phase SiC is expected to be soluble in fused alkali oxides (e.g. KOH) at a ratio of 1 part per 100 parts. No specific solubility information is available for this alpha-phase product.

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

    1 answer
    1. 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. Where can I find other Silicon- or Carbon-based materials?

    1 answer
    1. Sigma-Aldrich offers a wide variety of Silicon-, Carbon-, and other metal-based ceramic materials.

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

    1 answer
    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.

  8. Is Product 378097, Silicon carbide, alpha- or beta-phase?

    1 answer
    1. According to our supplier, this product has a hexagonal crystal structure (subclass, 6H) and is all alpha-phase.

  9. The particle size of Product 378097, Silicon carbide, is listed in "mesh". What does this mean?

    1 answer
    1. "Mesh" is a designation that refers to the particle size. It is related to the size screen -or mesh- through which the particles will pass. Product No. 378097 has a particle size of 200-450 mesh, which corresponds to a size of 74μm (200 mesh) to approximately 32μm (450 mesh).
