Abstract
A method of preparing silicon using silica includes placing silica in a reaction chamber; adding a reducing agent into the reaction chamber; feeding a material for impact into the reaction chamber and sealing the reaction chamber; and reducing the silica to silicon by allowing the material for impact to generate a physical impact inside the reaction chamber. The preparation method of silicon using silica does not employ a high-temperature high-pressure process and provides a preparation method of silicon by which the porous structure of the silica before a reduction reaction is maintained within the silicon even after the reaction.
