Jiangxi University of Science and Technology won the research and development right of band saw silicon powder recycling project
Recently, Jiangxi University of Science and Technology, in conjunction with the Jiangxi Geological Survey Research Institute and Jiangxi Xinhuaren Technology Co., Ltd., won a total victory in the bidding for major science and technology projects in Jiangxi Province, and won the first place with a good score. The research and development rights of the saw silicon powder recycling project. It is understood that the focus of this project is to solve the purification of silicon powder and the high oxidation of silicon ingot during the cutting process. According to the contract requirements, after the silicon powder of band saw is recovered, the silicon content of the silicon powder should be above 99.995%, and Must meet the quality standards for the production of solar polysilicon. It is understood that polysilicon materials are the most important photovoltaic materials in the world. With the widespread use of monocrystalline silicon and polycrystalline silicon in solar cells, the shortage of silicon raw materials is becoming more and more serious. Therefore, the research on the recycling of crystalline silicon corner scraps has become a worldwide one. research subject. At present, no country in the world has developed a truly effective approach. If this research is successful, it will fill a technological gap in China and will definitely play a positive role in promoting the photovoltaic industry in Jiangxi.
