Brief introduction

Micro silica ,also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal and wood chips. The smoke that results from furnace operation is collected and sold as silica fume, silica fume 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 active.
