This week, the domestic single crystal re feeding price range was 230000-247000 yuan / ton, and the average transaction price rose to 240000 yuan / ton, with a week-on-week increase of 2.30%; The price range of single crystal compact is 228000-245000 yuan / ton, and the average transaction price rises to 237600 yuan / ton, with a weekly increase of 2.19%. The price of silicon materials continued to rise this week, in which the average transaction price of single crystal re feeding, single crystal compact materials and single crystal cauliflower materials increased to varying degrees, and most silicon material production enterprises signed new orders. Some orders were signed until the end of January, others successively signed orders in February, and even some orders were signed until the beginning of March. (silicon branch)


Star Technology: Star Technology (002132. SZ) said on the investor interaction platform on January 17 that as of December 31, 2021, the number of shareholders of the company was 61600, and the company's silicone products are currently in trial production.






Xingfa group: Recently, it said on the investor interaction platform that the organic silicon new material integrated recycling project of Inner Mongolia Xingfa Technology Co., Ltd., the holding subsidiary of the company (including the new 400000 T / a organic silicon monomer production unit, Supporting 50000 T / a glyphosate unit and 300000 t / a ion-exchange membrane caustic soda unit) has obtained the energy evaluation approval.






Recently, its subsidiary Xingrui silicon materials announced the EIA of another 400000 ton project, mainly building silicon powder processing unit, monomer synthesis unit, monomer separation unit, dimethyl hydrolysis and cracking unit, methyl chloride synthesis unit, etc., and supporting the construction of methyl chloride and monomer product tank farm, acid-base tank farm, solid waste temporary storage, chemical warehouse, power distribution room, cooling tower Refrigeration unit and other auxiliary facilities. After the completion of the project, the annual output of silicone monomer will be 400000 tons, with a total monomer capacity of 800000 tons.






Dongyue silicon material (300821. SZ) said on the investor interaction platform on January 19 that up to now, the trial production of the company's fund-raising projects is being promoted in an orderly manner, and the company will arrange the trial production process in stages according to the product process and production process. Please pay attention to the company's regular report on performance.






With a total investment of 2.08 billion yuan, Zhongtian holding's downstream series of organic silicon products with an annual output of 290000 tons and the organic silicon monomer project with an annual output of 150000 tons entered the construction site at the end of June last year. At present, the phase I complex building and auxiliary building are basically completed, the civil engineering part has completed 80% of the overall construction progress, and some supporting projects and automatic production lines have been installed. The project is expected to be completed in mid-2022, It will be put into operation in the second half of the year.
