Silicon micropowder is made of pure quartz powder through advanced ultra-fine grinding process and is an inorganic non-metallic material with a wide range of uses. It has the advantages of excellent dielectric properties, low thermal expansion coefficient, high thermal conductivity and good suspension performance.

Due to its excellent physical properties, high chemical stability, unique optical properties and reasonable and controllable particle size distribution, it is widely used in optical glass, electronic packaging, electrical insulation, high-grade ceramics, paint coating, precision casting. , silicone rubber, pharmaceuticals, cosmetics, electronic components and ultra-large scale integrated circuits, mobile communications, laptops, aerospace and other production areas.

Silicon micropowder is also an important raw material for the production of polysilicon. The silicon micropowder is reacted with anhydrous hydrogen chloride (HCl) in a fluidized bed reactor to form trichlorosilane (SiHCl3), which is further purified and then reduced to form polycrystalline silicon in hydrogen. Polysilicon is the main raw material for solar cells in the photovoltaic industry.
