Micro Silica (Silica Fume): Production Applications

Aug 31, 2019  Micro silica is an amorphous polymorph of silica (SiO 2 / silicon di-oxide). It is also known as silica fume or condensed silica fume. It is an ultrafine powder collected as a by-product during the production of the silicon and ferrosilicon alloys. It consists of spherical particles having an average diameter of 150nm.

Silica fume - Wikipedia

Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product 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.
