The Silicon Industry Branch: the silicon material market expanded this week, the single crystal densifier fell by about 17%. According to the latest article issued by the Silicon Branch of China Nonferrous Metals Industry Association, the price range of domestic N-shaped materials this week is between 10.0 yuan and 110000 yuan per ton. the average transaction price was 103900 yuan / ton, and the weekly decline was 16.48%. The price range of single crystal densifier is 8.30-98000 yuan / ton, the average transaction price is 95900 yuan / ton, and the weekly decrease is 16.68%. The decline in the silicon market widened this week for the following reasons: first, the price of silicon wafers continued to decline, and most companies changed the signing mode to reduce safety inventory, resulting in a sharp reduction in demand for silicon. Second, capacity expansion is concentrated in the third quarter. Dongli, Jinnuo, Baofeng, Shangji and other enterprises will be put into production one after another. During the capacity climbing cycle, most enterprises face the risk of losses, and some enterprises may choose to delay production. Third, the upstream and downstream game intensifies, so that the recent shipment situation is not optimistic, and the accumulation of enterprise inventory makes it common to reduce prices and dump inventory. Therefore, under the pessimistic expectation, the company sold inventory to accelerate the decline of silicon prices.
