Silicon is generally obtained by decomposing chemical compounds like SiCl₄ in a molten atmosphere. The silicon obtained through this process may not be 100% pure and may contain impurities of about 1 part per million (ppm). To achieve higher purity, the zone refining technique is used. Process: -...
