| Abstract: | In order to research the effect on producing solar grade polycrystalline silicon, using vacuum induction melting process, the tests under different vacuum degree have been studied by vacuum induction melting equipments. According to ICP-OES results on phosphorus and several metal elements of raw materials and products, vacuum induction melting process can be used for solar grade polycrystalline silicon in ＂physical metallurgy＂ to improve the purity of silicon effectively. |
