SiO2 >95% LOI<2% higher flowability ensure quality accept to inspection by SGS.get the certificate fastest shipment Microsilica , also called silica fume .It is byproduct of silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips etc. The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled. Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specific surface area is 15~20 m2/kg, and it has extremely strong surface active.Microsilica can be used in a variety of cementation products, such as  refratory ,cement concrete, grouts, and mortars as well as elastomeric, polymer, ceramic and rubber applications.
