Overview of the Development of Silicon Micropowder Industry

   Silicon micropowder is a non-toxic, tasteless and pollution-free inorganic non-metallic material. Its main component is SiO2. It is a kind of non-metallic mineral products, which is made of natural quartz, fused silica and other raw materials through multiple processes such as primary selection, crushing, grinding and precision classification. Silicon micropowder, as an inorganic non-metallic mineral functional powder material, can be widely used in fields such as electronic materials, electrical insulation materials, adhesives, special ceramics, precision casting, paint coatings, ink, silicone rubber, functional rubber, advanced building materials, etc.

At present, only a few countries in the world, such as China, Japan, South Korea, and the United States, have the production capacity of silicon powder. The quartz sand resources in China are mainly distributed in Fengyang, Anhui Province, Donghai, Jiangsu Province, Guangxi, and other places. The domestic downstream market is still concentrated in the economically developed areas such as East China and South China, while the domestic relatively powerful silicon powder manufacturers are mainly distributed in economically developed areas and areas rich in raw materials, concentrated in Jiangsu Lianyungang, Anhui Fengyang, Zhejiang Huzhou and other areas. Among them, Donghai County of Jiangsu Lianyungang is the largest silicon powder production base in China, and has been engaged in the research, development Production area.
