Factors such as impurity content in silicon, crystal phase, morphology and particle size distribution of silicon powder affect the synthesis of M2 to a large extent. The quality and high-end development of the organic silicon industry urgently needs high-quality industrial silicon raw materials. As high-quality raw materials become less and less, it is becoming more and more difficult to control the content of trace impurities in silicon through raw material optimization. It is urgent to combine the existing industrial silicon production processes and adopt enhanced smelting and intensified refining technologies to develop industrial silicon production process micro-impurities. Element (especially Ti, P) control and effective removal technology to meet the increasing demand for organic silicon, ensure the healthy development of the organic silicon industry, and promote the progress and improvement of industrial silicon production technology. In addition, studying the internal laws between the regulation of the precipitated phase during the solidification of silicon melts and the physical properties of the silicon powder, and the production of low-cost organic silicon products, will improve the overall technical level of the organic silicon industry in my country and help organic silicon The rise of the industry is of great significance to enhance the international competitiveness of my country's organic silicon industry and related industrial chains.
