how to separate silicon from sand

The enthalpy of formation of silicon is -911 kJ/mol. This means that converting the elements Si and O2 to SiO2 gives out a LOT of energy. To reverse this, we have to put that energy back (and some more, courtesy of thermodynamics) which really mea...

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.
