Slag refining of silicon has been modified in recent years by combining the process with solvent refining, in which an alloy of silicon is first treated by slag and then solidified under controlled conditions to yield high-purity silicon crystals. This paper discusses the effect of alloying elements on the efficiency of slag treatment. A set of criteria are established and quantified for potential alloying elements to guide their proper selection.

硅合金炉渣精炼综述

近年来，通过将该工艺与溶剂精炼相结合，对硅的炉渣精炼进行了改进，其中硅合金首先用炉渣处理，然后在受控条件下固化，以产生高纯度的硅晶体。本文讨论了合金元素对炉渣处理效率的影响。为潜在的合金元素建立并量化了一组标准，以指导它们的正确选择。
