The present invention relates to a process for removing impurities from molten silicon by treatment of molten silicon contained in a vessel with a slag having the capability of removing the impurities, particularly boron, from molten silicon. The slag is continuously or substantially continuously added to the molten silicon and then continuously or substantially continuously inactivated or removed from the silicon melt as soon as equilibrium between the slag and molten silicon is reached with respect to the impurity elements or element to be removed.
(ZH) 本发明涉及一种使用能从熔化硅中除去杂质，特别是能除去硼的渣来处理容器中所含的熔化硅以从熔化硅中除去杂质的方法，其中所述的渣是连续地或基本上连续地被加入到熔化硅中，并且，当该渣和熔化硅之间相对于杂质元素或要被除去的元素达到平衡时，该渣是连续地或基本上连续地从熔化硅中被钝化或被除去。
