基于电子束熔化和精炼的技术已被用来精炼N型废硅，以生产适合光伏应用的材料。本文描述了实验设置和方法，并与三个实验的实验结果一起呈现。给出了从其中一项实验的嵌入式热电偶获得的温度数据。采用中子衍射分析来测量三个铸件的残余应变。采用有限元热和应力数学模型来预测残余应力分布。
A technique based on electron beam melting and refining has been used to refine N-type scrap silicon for the purpose of producing material suitable for photovoltaic applications. In this paper, the experimental setup and methodology are described and are presented together with the experimental results for three experiments. Temperature data obtained from embedded thermocouples for one of the experiments is presented. Neutron diffraction analysis was employed to measure the residual strain in the three castings. Finite element thermal and stress mathematical models are employed to predict the residual stress distribution.
