General description

Silicon carbide (SiC) is a semiconductor based material that consists of a closed packed stacking of double layers of silicon and carbon. It has an excellent thermo-mechanical property that makes it useful in a variety of electronic and optoelectronic applications.[1][2]

Application

SiC is majorly used as a base material for applications such as micro-structures[3], opto-electronic devices(OLEDs), UV detectors[4][5], high temperature electronics (nuclear electronics)[6], high frequency devices[7]

Questions

1–7 of 7 Questions  
  1. 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.

  4. 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).

  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.
