多晶硅是用工业硅(硅粉)通过化学、物理途径提纯制得,生产所用的主要配套原料是H_2和HCl。多晶硅主要用于生产单晶硅和卫星太阳能电池的材料。 单晶硅即硅半导体,是多晶硅的衍生产品,是制造集成电路和电子元件的优质材料。 Polysilicon is obtained through the purification of industrial silicon (silica fume) through chemical and physical methods. The main supporting raw materials for production are H2 and HCl. Polysilicon is mainly used for the production of monocrystalline silicon and satellite solar cell materials. Monocrystalline silicon, or silicon semiconductor, is a derivative of polysilicon and is a good material for the manufacture of integrated circuits and electronic components.
