Discussion on chlorohydration technology

However, I believe that polycrystalline materials are facing a major challenge at the moment, namely the handling of the by-product silicon tetrachloride. At present, the consumption of silicon tetrachloride in China is fixed; to use a large amount of silicon tetrachloride, it is necessary to convert it into trichlorosilane. However, this technology is not yet mature in China and is mainly under control of some countries in Europe and America. The method we use here involves carrying out both the synthesis of trichlorosilane and the hydrogenation of silicon tetrachloride in the same furnace. We claim to be the first in China to adopt this approach; experts in this field are welcome to join in the discussion. Thank you
Is there any relevant information that can be shared? I’ve been thinking about this issue lately, so let’s take the opportunity to discuss it
Hehe, I didn’t expect there to be so many discussions about polysilicon on this Haichuan forum. I came here to learn; it’s great to see so many experts here – I’ve finally found a good community to belong to. I work in the testing of polysilicon, and I’m currently feeling lost. I don’t know what polycrystalline silicon production processes everyone is using. I would like to ask the seniors: can N-type material be produced using P-type or hybrid seed crystals? I hope D can give me more guidance! Thank you!
I’m eating too, haha. We can chat when we have time. 1# wangjibo1314
Are there any issues worth paying attention to regarding chlorohydration at the moment? I’d like to know about my current work on synthesis segments
