Technical characteristics of silicon micro powder industry

Due to its excellent performance as a functional powder filling material, fused silica micro powder products play a crucial role in the performance of downstream products. Therefore, research and development work on silica micro powder products has been ongoing, aiming to improve product fineness and purity, simplify production processes, and reduce costs. These are all directions for technological innovation. In this regard, domestic enterprises represented by Lianyungang Haosen Mineral Products Co., Ltd. have conducted numerous technological breakthroughs and accumulated a lot of experience. Multiple technological breakthroughs have been achieved in terms of diversifying production materials, improving product purity, and innovating production processes.

Although the production capacity and technological level of the domestic silicon micro powder industry have grown rapidly in recent years, its competitiveness in the international market is still weak. Developed countries such as Japan have monopolized the market for high value-added silicon micro powder products by leveraging their technological and research and development advantages. At the same time, it should be noted that due to the lack of a national association for the silicon micro powder industry, the industry's technical standards have not been established, and product standards have not been unified, which to some extent restricts the rapid development of the industry and further improvement of its technological level.

Lianyungang Haosen adopts advanced production processes such as quartz stone washing, breakage, sun drying/drying, impurity removal, compounding/melting, dry ball milling, classifier classification, impurity removal/compounding mixing, packaging and storage. At present, it has developed and produced more than 30 specifications of silicon powder products, including crystalline silicon powder, molten silicon powder, active (modified) silicon powder, high-purity silicon powder, soft composite silicon powder, electronic grade silicon powder, electrical grade silicon powder, ultra-fine silicon powder, spherical silicon powder, glass powder, cristobalite powder, high-purity quartz sand, fused silica sand and so on. It is oriented to hundreds of different industries, including adhesives, electronic materials, electrical insulation materials, liquid crystal glass, medical materials, dental materials, precision casting, paint coatings, functional rubber, plastics, chemical materials, nanomaterials, building materials and so on. The product marketing covers more than 20 provinces and regions across the country, and is exported to countries such as Asia, Europe, the United States, and Africa.
