Questions

1–7 of 7 Questions  

  1. 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.

      Helpful?

  2. 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.

  3. 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).

  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.
