Silicon carbide is an extremely hard bluish-black insoluble crystalline substanceproduced by heating carbon with sand at a high temperature andused as an abrasive and refractory material. There are many appliions of silicon carbide, such as slide bearings, sealing rings, wear parts, sintering aids, crucibles, semiconductor appliions, heating elements, burner nozzles, heat exchangers.
2009/1/28· The unreacted silicon in our samples is likely to be an insulating phase fraction with no electronic and almost no phononic contributions to the specific heat at low temperatures. Therefore, a residual contribution caused by this phase fraction cannot easily explain the values for γ res found in the specific-heat analysis assuming a BCS-like scenario given in [ 11 , 15 ], as mentioned in the
