    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. These react spontaneously with air to give spectacular but harmless ...

    Isolating silicon from silica is the first step in the production of silicone. This is done by heating a large volume of quartz sand to temperatures as high as 1800˚C. The result is pure, isolated silicon, which is allowed to cool and then ground into a fine powder. To make silicone, this fine silicon powder is combined with methyl chloride ...

    Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics.

  • How Is Silicon Obtained? | eHow

    The Production of Pure Silicon. Pure silicon is produced by heating silicon dioxide along with carbon in an arc furnace at around 1900 degrees Celsius. The heat causes the oxygen in the silicon dioxide to split from the silicon and bond with the carbon. Hence, the outputs of this process are pure silicon, carbon monoxide and carbon dioxide.
