Micro Silica

Micro Silica is a byproduct from silicon metal or ferrosilicon industries, is an amorphous silicon dioxide – SiO2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz. As the molten metal is produced, a silica-based gas is emitted. This gaseous fume, as it rises, cools rapidly and forms extremely minute, amorphous, spherical particles. The Micro Silica is collected in a bag house, a system for filtering the hot air and gases vented from the furnace. The Micro Silica is imported from China to production site.
