Microsilica (Silica Fume) is a co-product of the silicon metal and ferro silicon industry, is an amorphous silicon dioxide(SiO2) which is generated as a gas in submerged electrical are furnaces during the reduction of very pure quarta. This gas vapor is condensed in bag house collectors as very fine gray to off-white powder of spherical particles that average 0.14 microns in diameter. Microsilica(Silica Fume) is used in a varity of cementitious (concrete, grouts and mortars, such like parking garages, bridge decks, marine structures,slabs roadway), elastomer, polymer, refractory and ceramic applications.
