Floor 49: Posted on 2008-10-6 at 19:55. This article was posted by Sankeng. Yongxiang Silicon Industry has already started production at a rate of 1000 tons per year; more than 3 tons were produced in the first batch. The goal is to reach 10,000 tons per year by the end of this century. It is said that the industry in Leshan is quite prosperous.

Floor 59: Posted on 2008-10-11 at 02:06. This article was posted by HappyFatBoys. Luoyang Zhongsi High-Tech seems to have a production capacity of 3000 tons per year. Initially, it was said to have a capacity of 300 tons in the surrounding area; later, that capacity was increased by 700 tons. There’s also a facility with a capacity of 1000 tons being built near Luoyang High-Tech Zone – I’m not sure if that’s true. The information seems reliable.

Post on Floor 69, published on 2008-10-18 at 16:21. This article was posted by txdaibin. As far as I know, Jiangsu Zhongneng is a very large producer in China, with an annual production capacity of 4,500 tons; it seems that they plan to increase this capacity to 6,000 tons by the end of this year
What a sad post; no one has replied.
The polysilicon project in Qujing, Yunnan is currently in the process of site preparation, with plans to start operations in December next year
In Qujing, Yunnan, the polysilicon production capacity will be 3,000 T/year; the investment for the first phase is 3.3 billion yuan, while the total investment for the third phase amounts to 10 billion yuan. By then, the production capacity will reach 10,000 T/year
I heard that this project is extremely energy-intensive; China has limited energy resources – why then pursue its development so vigorously?
It can be seen that the development of polysilicon in our country is quite good
Do you know what technology they use? It seems unlikely to achieve 10,000 t/a per year; however, I hope they will succeed
