microsilica 85 grade

Silica fume, also known as microsilica, (CAS number 6901264-2, EINECS number 273761-1) is an amorphous (noncrystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a byproduct of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. The main field of application is as pozzolanic material for high performance concrete ,refractory,rubber,oil paint, etc.

Silica Fume is a pozzolanic material that consists primarily of fine silicon dioxide particles in a non-crystalline form.

Silica Fume meets the requirements of ASTM C-1240 and contains a minimum of 85% silicon dioxide (SiO2).

Silica Fume CAS # : 69012-64-2

Application of Microsilica

– Bridge
– Oil well
– Tunnel
– High-speed railways
– High-Rise structures
– Marine platform
– Hydropower station
– Refractory Industry
– Others
