随着光伏产业的快速发展,对太阳能级硅原材料的需求不断增加。熔析结晶法作为一种冶金硅提纯的新工艺越来越受到重视。熔析结晶法是利用冶金硅中杂质元素的偏析行为,选择适当的熔析介质,使杂质元素从冶金硅中偏析到熔析介质中,进而获得高纯硅的方法。详细介绍了Al-Si、Sn-Si、Cu-Si、Fe-Si和Ca-Si等熔析体系对冶金硅提纯的研究现状,比较了各种介质体系的优缺点。同时针对熔析结晶法提纯硅存在的问题提出了一些建议。

The rapid development of photovoltaic industry results in the great demand of silicon feedstock for solar cells.Solvent refining of silicon as a new purification process,will be more emphasized.Solvent refining of silicon is a purification process in which recrystallized silicon takes place from the supersaturated melt depending on the segregation behavior of different elements between silicon and melt.In this paper,the research process on the main solvent systems,such as Al-Si,Sn-Si,Cu-Si,Fe-Si,Ca-Si,et al,is introduced in detail presently.Comparisons with the advantage and disadvantage of different solvent systems are discussed.At last,some suggestions were put forward for further purification.
