目前多晶硅供应十分紧张,现货交易价已达80～100美元/公斤,甚至超过100美元/公斤,故各多晶生产厂家都在积极扩建。本月初瓦克硅电子(Wacker Siltronic)公司发表建设世界最大多晶硅厂的计划,准备在美国的波特兰特厂投资8000万美元建设年产5000吨多晶的工厂(是否在该厂原有多晶2000吨/年左右的基础上扩建,不详一摘者注)。该厂准备明年开春动工,1987年出产品,采用西门子工艺。
The current supply of polysilicon is very tight, the spot transaction price has reached 80 to 100 US dollars / kg, or even more than 100 US dollars / kg, so the polycrystalline manufacturers are actively expanding. Earlier this month, Wacker Siltronic Inc. announced plans to build the world’s largest polysilicon plant and plans to invest 80 million U.S. dollars at Portland Plant in the United States to build a 5,000-tonne polycrystalline plant Crystal 2000 tons / year on the basis of the expansion, not a pick person note). The plant is ready to start next spring, a product in 1987, the use of Siemens technology.
