Objects of the research were fundamental studies on production of semiconductor silicon from silicon including in molten pig iron.Iron including silicon and saturated by carbon are melted in hydrogen atmosphere and chlorine was introduced into the bottom of the molten iron. Experimental results are as follows :(1)Reaction rate can be expressed as first order equation for silicon content in the iron.(2)Relation between reaction rate and temperature can be expressed by Arrhenius equation.(3)Apparent activation energy was 60 kcal/mol.(4)Over 50 ml/min of flow rate, the reaction rate was not affected by the flow rate of the reaction gas.(5)The larger amount of molten iron, the more efficiency of chlorine gas.(6)The procedure was applied to removal of copper from molten steel, however the copper did not remove.

本课题的研究对象是用含熔生铁的硅生产半导体硅的基础研究。将含硅和碳饱和的铁在氢气气氛中熔化，并在铁液底部加入氯。实验结果表明：(1)反应速率可表示为铁中硅含量的一级方程。(2)反应速率与温度的关系可用Arrhenius方程表示。(3)表观活化能为60 kcal/mol。(4)在流量大于50 ml/min时，反应速率不受反应气体流量的影响。(5)铁液量越大，氯气效率越高。该方法用于从钢液中除去铜，但铜没有除去。
