太阳能级多晶硅生产工艺的节能降耗综述

Review of Saving Energy Solar Grade Polysilicon Production Technology

太阳能用多晶硅来自石英矿或者硅石矿,进行冶炼得到金属硅,然后将金属硅提纯到太阳能级多晶硅。文章以西门子改良法制备多晶硅基础,从生产技术和管理的角度,分析总结了该生产工艺节能降耗的必要性、途径和方法,探索集约型的多晶硅生产。

Solar polysilicon from the quartz mine or silica mine, silicon metal smelting, metal silicon purification to solar-grade polysilicon. In the paper, basis for Siemens improved silicon prepared, from the point of view of production technology and management, discussed the necessity of the production process energy saving, ways and means, explored intensive polysilicon production,
