Low price microsilica wt-94u

Microsilica (Silica Fume) is a mineral composed of ultrafine amorphous spheres of silicon dioxide (SiO2), produced during the manufacture of silicon or ferrosilicon. The average particle diameter is 0.15-0.20 um.

Silica Fume originates from the oxidation of the SiO gas produced during the fabrication of Silicon, Ferrosilicon alloys and CaSi alloys in electric furnaces. The SiO2 formed is then condensed into spherical particles and recovered in bag house filters.

Silica Fume consists in individual ultrafine particles of silicon dioxide with a high specific surface and an average diameter of 150nm which gives Silica Fume its high pozzolanic properties.

Specific Surface Area is ranging from 15, 000 to 20, 000 m2/kg, has dynamic surface activity.


Low price microsilica wt-94u

1) Concrete or shotcrete

Increase its density and strength, improve the performance on its durability,impact resistance, corrosion resistance, anti-permeability and frost resistance etc

2) Refractory material & Ceramics material
