| 1 | Purification of solar cell silicon materials through filtration显示文摘Silicon is the material most commonly used in the manufacturing of photovoltaic (PV) cells. In the current study, laboratory experiments of purification of solar cell silicon materials through filtration are carried out. Inclusion removal from silicon was investigated. The purpose is to achieve clean silicon materials for solar cells. Silicon samples and filter samples were analyzed using microscope observation, EPMA, and X-ray detection. Silicon nitride (Si3N4) and silicon carbide (SiC) particles are the main non-metallic inclusions present in top-cut silicon scrap. Almost all inclusions larger than 10 μm can be removed from silicon by the porous foam filter. In mass fraction, more than 90% inclusions are removed. Si3N4 particles are mainly removed on the top surface of the filter, and SiC particles are mainly removed by entering the pores and attaching to the filter material. SiC inclusions are not only simply attached on the surface of the filter material, but are found also inside the filter material. There are SiC bridges near the filter materials. These bridges may fill the spaces between filter material, and this will further retard inclusions passing through the filter. Three-dimensional turbulent fluid flow and inclusion motion in the filter was calculated. Both experimental observation and fluid flow simulation indicate that most of the inclusions are entrapped at the upper part of the filter. | CIFTJA Arjan ENGH Thorvald Abel KVITHYLD Anne | 2006 | Rare Metals2006，25，z1： | 5 |
| 2 | 纯铝与石墨、SiC和Al_2O_3的润湿性(英文)显示文摘纯铝与过滤材料和夹杂物之间的润湿性是影响铝的过滤性能的重要因素。在10-8bar真空条件下于1000~1300°C,研究液态铝与氧化铝、SiC和石墨之间的润湿角。为了描述铝的过滤和浇铸等在低温条件下铝与陶瓷的润湿行为,使用半经验模型进行研究。计算出的700°C的纯铝与氧化铝的润湿角为97°,与玻璃体石墨的为92°,与单晶和多晶石墨的为126°,与单晶的为SiC79°。结果表明:在浇铸温度下铝不能润湿氧化铝和石墨(或者Al4C3),但可以润湿SiC。因此,为了让铝能够浸润过滤材料,在铝过滤时需要施加一个压力差作为推动力。提高温度也可以改善铝与陶瓷间的润湿性。 | 包萨日娜 唐恺 Anne KVITHYLD Thorvald ENGH Merete TANGSTAD | 2012 | Transactions of Nonferrous Metals Society of China2012，22，8： | 4 |
| 3 | 铝的润湿行为以及Al_2O_3和SiC陶瓷过滤器的过滤行为(英文)显示文摘检测了工业用Al2O3过滤器和SiC过滤器与液态铝的润湿性并在工厂使用以上2种陶瓷过滤器过滤铝液。实验结果表明:Si C过滤器比Al2O3过滤器更易于润湿液态铝。提高液态铝与过滤器的润湿性有助于铝液透过过滤器,提高夹杂物的去除率,同时,易于去除与铝不浸润的杂质。 | 包萨日娜 Martin SYVERTSEN Anne KVITHYLD Thorvald ENGH | 2014 | Transactions of Nonferrous Metals Society of China2014，24，12： | 3 |
