Chemistry of Silicon (Z=14) Chemistry LibreTexts

Chemistry of Silicon (Z=14) Chemistry LibreTexts

Silica is the most prevalent form of naturally occurring silicon. Silica is a strongly bonded compound and it requires a good deal of energy to extract the silicon out of the silica complex. The principal means of this extraction is via a chemical reaction at a very high temperature. The synthesis of silicon is fundamentally a two step process.
