Electron beam vacuum melting is to use the huge local energy of the electron beam (103~106W/cm3) to volatilize impurities (such as phosphorus and aluminum) whose vapor pressure is higher than that of silicon (the vapor pressure of 1700K silicon is 0.0689Pa). Additionally, localized overheating can remove oxides. The basic principle of the electron beam melting … Read More
