Silicon : definition of Silicon and synonyms of Silicon

Using this method, silicon carbide (SiC) may also form from an excess of carbon in one or both of the following ways: SiO 2 + C → SiO + CO or SiO + 2 C → SiC + CO. However, provided the concentration of SiO 2 is kept high, the silicon carbide can be eliminated by the chemical reaction 2 SiC + SiO 2 → 3 Si + 2 …
