    Aug 01, 2014· Calcium hydroxide was added into the reaction to react with the silicon for immobilising the silicon in solid phase, which can then help with the separation of Si from Al. As shown in Fig. 5 , the alumina extraction ratio increased by increasing the C/S to , and then remained nearly constant at approximately 91% with higher C/S ratios.

  • 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.
