SF-92:92% Densified Silica Fume

Silica fume is a co-product from the production of silicon or ferrosilicon metal. 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.

Silica fume powder is black or gray in color, and is available in several product forms and packaging options. Our products include:
Undensified Silica Fume (320-360kg/m³)
Densified Silica Fume (630-680 kg/m³)

Silica Fume Application:
Concrete, Refractory, High Performance Concrete, Oil and Gas Industry, Ceramics, Concrete Roofing, Wall boards, Cementation Repair Products, Concrete Tile & Panels, FCB, Shotcrete, Polymers & Elastomers and (SCC) Self-Compacting Concrete.
