 Silica FumeSiO2
1. Instruction
  • Microsilica , also called silica fume or micro silica, is a byproduct ofproducing silicon metal or ferrosilicon alloys.
  • Silicon metal and alloys are produced in electric furnaces. The rawmaterials are quartz, coal, and woodchips.
  • The smoke that results from furnace operation is collected and sold assilica fume, rather than being land filled.
  • Silica fume consists primarily of amorphous (non-crystalline) silicondioxide (SiO2), its average granule diameter is 0.15~0.20 µm,specificsurface area is 15000~20000 m2/kg, and it has extremely strongsurface active.
  • Microsilica can be used in a variety of cementation products, such asconcrete, grouts, and mortars as well as elastomeric, polymer, refractory,ceramic and rubber applications.
  • HS No.: 28112200 China Origin, microsilica meets the requirements ofASTM C-1240.
  • Microsilica CAS#: 69012-64-2
2. Main function
    • Microsilica in refractory enhancing thefluid of pouring refractory, reducing the volume of used water, be easy toshape, and raising the production efficiency.
    • Because of its ultra microstructure forgap filling, the compact and intensity of refractory gain rising by a wademargin.
    • Microsilica in refractory is a highlyeffective pozzolanic material, so it's easy to come into being Mullet Phase,under the premise that Al2O3 exists, enhance elevated temperature strength andthermal shock of refractory.
    • Microsilica in refractory is used in Microsilica in refractory is used inunshaped,shapedgunned refractory materials to improves adhesion in castablesand minimizes rebound loss.
