Silicon : definition of Silicon and synonyms of Silicon

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 CO. As noted above, metallurgical grade silicon "metal" has its primary use in the aluminum casting industry to make aluminum-silicon alloy parts.

Is silicon considered to be metal or non-metal? - Quora

Silicon is an insulator.This is based on the fact that silicon’s Fermi Level (the energy at which silicon’s electrons have the probability of having is 0.5) is loed within its Energy gap (also equivalent to the HOMO-LUMO separation), which is essentially by definition, a place where electrons are not even allowed to be in. Silicon’s band gap is about 1.1 eV.
