The purification of metallurgical grade silicon by electron beam melting

Metallurgical grade silicon (MG-Si) is obtained from the reduction of silica (SiO2) in a voltaic arc furnace. The impurities are inherent to the reduction process and they are also dependent on the quality of the initial materials. Among other applications, silicon is used as a substrate for photovo...
