自上世纪七十年代爆发得能源危机以来，各国政府加强了新能源得开发和利用，人们把眼光投向了可再生能源，希望可再生能源能改变人类的能源结构，维持长远得可持续发展。其中太阳能分布广泛、储量大，清洁无污染等优点成为解决能源危机得首选新能源，目前，以利用太阳能为核心得各种新能源得研究和开发正在世界蓬勃发展。世界光伏产业对原材料太阳能级多晶硅得需求量大大得增加，如今太阳能级多晶硅的需求量远远超过了电子级多晶硅，因此研究高效率低成本的太阳能级多晶硅的制备方法具重大意义。

Since the outbreak of the energy crisis in 1970s, the governments of various countries have strengthened the development and utilization of new energy, people have paid their attention to renewable energy, and hope renewable energy being able to change the energy structure of the human being, so as to maintain long-term sustainable development. Of which solar energy has become the preferred new energy for solving energy crisis due to its wide distribution, large reserve, clean and pollution-free, etc. At present, the research and development of various new energies, which take solar energy as the core, is booming in the world. As a result the demand of global photovoltaic industry for raw materials, solar grade polysilicon is increased significantly, and now the demand for solar grade polysilicon is far more than electronic-grade polysilicon, therefore the research on the fabrication method of high efficiency, low cost solar grade polysilicon with significant preparation has great significance.多晶硅制备的主流技术有改良西门子法和硅烷法，但都被国外厂家所垄断，他们既不提供技术也不进行太阳能级多晶硅制合作，导致我国原料生产这一块严重受制于人，到目前为止其核心技术我国还是没有完全掌握。发展新的制备工艺是解决我国多晶硅产业的唯一出路，冶金法制备太阳能级多晶硅具有低成本污染小等优点，但存在工艺上不成熟等问题，因此开发良好的熔炼工艺具有重要得意义。

The mainstream technologies for fabricating polysilicon include improved Siemens process and silane process, but both of them are monopolized by foreign manufacturers, these manufacturers neither provide technologies nor carry out co-operation in solar grade polysilicon fabrication, resulting in the production of raw materials in China being limited severely by them, so far the core fabrication technology of solar grade polysilicon in China still did not be fully mastered. The only way out for China to develop polisilicon industry is to develop new preparation process for it. The metallurgy process for fabricating solar grade polysilicon has the advantages such as low-cost and low pollution, but there is the issue of immature technology, as a result to develop good melting process has important significance.

本文介绍冶金法制备太阳能级多晶硅生长的工艺，冶金法制备的种类，以及跟传统制备太阳能级多晶硅制备方法进行比较，详细叙述冶金法中的真空熔炼的工艺，对不同真空状态、保温时间、熔炼功率等熔炼参数对各种杂质元素的去除效果的影响。综合可得，真空熔炼确实是个提纯硅料的有效方法；并且采用合适的工艺是可以获得良好的效果，在铺助以定向凝固可以将金属杂质进一步去除，满足太阳能级硅材料的要求。

This article presents the growth process of solar grade polysilicon using metallurgy process, the types that can be fabricated with metallurgy process, and makes comparison of metallurgy process with traditional fabrication processes for fabricating solar grade polysilicon. In addition the article describes in detail the vacuum melting process in the metallurgy process, and the effects of various melting parameters such as different vacuum state, temperature holding time, melting power on the removal of various impurity elements. As a whole, vacuum melting is indeed a valid method for purifying silicon; and good results can be got by using appropriate process technology. In the case of combining with directional solidification, metal impurities can be removed further so as to meet the requirements for solar grade silicon material.
