Upgrade Metallurgical Grade Siliconng, vacuum treatment, plasma refining, and electron beam treatment; these technologies are used to refine metallurgical-grade silicon. Purification is also very important in the production process; a solidification process is used in purification to obtain highly pure silicon.
