 Applications 1. A micrometer silica fume made of silicon microwires used in rechargeable lithium ion battery anode material, or graphite coated the surface of the micrometer silica fume used as a rechargeable lithium ion battery anode materials to improve rechargeable lithium battery for more than three times the capacitance and charge-discharge number of cycles; 2 micrometer silica fume used in high temperature coatings and refractories; 3 um silicon can be applied to the coating to form a silicon microfilm, a large number of applications to the solar above; 4 um the formation of silicon carbide --- diamond composite material, silicon powder and diamond under high pressure mixed and used as a cutting tool.

The main characteristics of micro-silica fume, ultrafine silicon powder prepared through a special process, the product high purity, good dispersion and small particle size, distribution, large surface area and high surface activity, the apparent low density and good activity. Micrometer silicon BNY-Si-001 with a compound such as graphite, carbon microtubes, made of lithium-ion battery anode material for lithium-ion battery capacity and cycle times, extend the service life. Is a new generation of optoelectronic semiconductor materials, with a wide gap.
