94% Undensified Silica Fume

Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production.

96% Undensified Silica Fume

Undensified Silica Fume is mainly composed of SiO2 wollastonite, particle characteristics is ultrafine powder, the vast majority is less than 1 um, the average particle size is 0.1 um, has very high specific surface area (300-400 M2 / kg) and pozzolanic activity.

Typical value is just for reference.
