Contact reaction of silicon carbide with fused copper

Conclusions

  1. 1.

    We have studied the contact reaction and wetting of single crystals and polycrystalline silicon carbide by liquid copper.

  2. 2.

    It is shown that pure copper decomposes silicon carbide to form a Cu-Si alloy and graphite.

  3. 3.

    The presence of small amounts of silicon in copper suppresses the reaction of copper with silicon carbide.

  4. 4.

    We have verified our hypothesis that the resistance to copper of silicon carbide material containing small amounts of free silicon is greater than that of single-phase material with the same volumetric content of silicon carbide.
