Microsilica (silica fume) is a byproduct of producing silicon metal or ferrosilicon alloys in smelters using electric arc furnaces.The smoke that results from furnace operation is collected and sold as silica fume, which consists primarily of amorphous(non-crystalline) silicon dioxide(SiO2). Its average granule diameter is 0.15~0.20um,specific surface area is 15000~20000m2/kg,and it has extremely strong surface activity.
