Is Silicon Carbide a Good Conductor of Electricity

Silicon carbide is an extremely hard bluish-black insoluble crystalline substance produced 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.

Ethylene oxide - Wikipedia

Union Carbide (currently a division of Dow Chemical Company) was the first company to develop the direct oxidation process. [68] A similar production method was developed by Scientific Design Co., but it received wider use because of the licensing system – it accounts for 25% of the world''s production and for 75% of world''s licensed production of ethylene oxide.

A Heterogeneous Process for the Synthesis of Silicon …

Study of the heterogeneous reaction of SiO2 with activated carbon fibers has shown that the heterophase reaction (SiO2 (gas), SiO (gas) + C) gave rise to polycrystalline fibers of α- and β-SiC, whereas the homophase reaction of SiO with CO on a Si cupel led to the growth of filament crystals of α-SiC. In agreement with the proposed mechanism for the origin and growth of SiC crystals, the
