Micro Silica
1.Silica fume *5%**8%
2.High electrical resistivity
3.Low permeability
3.Superior resistance to chemical attack
Micro silica for Concrete/Refractory
1.Instruction
Microsilica , also called silica fume, is a byproduct of producing silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal, and woodchips. The smoke that results from furnace operation is collected and sold as silica fume, rather than being land filled. Microsilica consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.*5~0.*0 µm,specific surface area is ****0~****0 m2/kg, and it has extremely strong surface active.
