Ultrafast carbothermal reduction of silica to silicon using a CO2 laser beam
Abstract We report the extraction of silicon via a carbothermal reduction process using a CO2 laser beam as a heat source. The surface of a mixture of silica and carbon black powder became brown after laser beam irradiation for a few tens of seconds, and clear peaks of crystalline silicon were obser...
