Frequently Asked Questions

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. http://www.sigmaaldrich.com/etc/medialib/docs/Sigma-Aldrich/General_Information/shippingandlong-termstoragev3.Par.0001.File.tmp/shippingandlong-termstoragev3.pdf
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. These documents are located on the product detail page under Useful Links & Tools. Click on the following link to search for a Certificate of Analysis. Please click the following link to see the details on our Product Dating Information.
How do I get lot-specific information or a Certificate of Analysis?
A Certificate of Analysis is available by lot number and can be obtained through our Advanced Search Option: http://www.sigmaaldrich.com/catalog/AdvancedSearchPage.do
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. 
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, or search here. 
My question is not addressed here, how can I contact Technical Service for assistance?
Use the option to the right to "Ask a Question" by email of a Technical Service Scientist.
Where can I find other Silicon- or Carbon-based materials?
Sigma-Aldrich offers a wide variety of Silicon-, Carbon-, and other metal-based ceramic materials. A complete list of materials (categorized by metal) can be reviewed at the following link: http://www.sigmaaldrich.com/materials-science/material-science-products.html?TablePage=101268325.
What solvents can I use to dissolve Product 378097, Silicon carbide ?
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.
What applications can Product 378097, Silicon carbide, be used for?
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.). Additional information on the general properties and uses of Silicon carbide has been included in Material Matters (Vo. 4, No. 2). This publication can be reviewed at the following link: http://www.sigmaaldrich.com/etc/medialib/docs/Aldrich/Brochure/al_material_matters_v4n2.Par.0001.File.tmp/al_material_matters_v4n2.pdf.
Is Product 378097, Silicon carbide, alpha- or beta-phase?
According to our supplier, this product has a hexagonal crystal structure (subclass, 6H) and is all alpha-phase.
The particle size of Product 378097, Silicon carbide, is listed in "mesh." What does this mean?
"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). A particle size conversion chart can be accessed at the following link: http://www.sigmaaldrich.com/chemistry/stockroom-reagents/learning-center/technical-library/particle-size-conversion.html.
