Making silicon and silanes from sand – teacher notes
Making silicon and silanes from sand – teacher notes Introduction Magnesium and sand are heated together, and silicon is produced by an exothermic reaction. The product is placed in acid to remove magnesium oxide and unreacted magnesium. Small amounts of silanes are produced by the reaction of magnesium silicide (a side product) with the acid.

Silicone: A Guide to Production, Uses and Benefits - SIMTEC
1 Step 1: Isolate Silicon From Silica. Isolating silicon from silica is the first step in producing silicone. To achieve this, a large volume of quartz sand is heated to temperatures as high as 1800 degrees Celsius. Pure, isolated silicon is the result. Once it cools, manufacturers can grind it into fine powder.
