What is Silica Fume?

Silica fume is a co-product from the production of silicon or ferrosilicon metal. Silica fume is a mineral admixture, a very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g.  Silica fume is used in a variety of cementitious concrete, grouts and mortars, refractory, elastomer and polymer applications. Silica fume powder is gray to off-white in color.

When silica fume is used in concrete, shotcrete and repair products, it performs as a filler, improving the physical structure by occupying the spaces between the cement particles, and as a reacting chemical (pozzolanic) to create greater strength and durability to concrete.

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.

Silica Fume is an amorphous product.  Its color ranges from white to dark grey and is available in densified and undensified forms.

Microsilica in application of Refractories                


Traditional refractories in many pores,microsilica fume filling in the pores ,increased bulk density and porosity of lower intensity can significantly enhanced.

Microsilica with strong activity in the water yo form colloidal particles,adding suitable dispersant can be strengthened liquidity, thereby improving performance casting.

Microsilica fume formed easily in the water-Si-oh and has strong hydrophilicity and activity can enhance the coshesion refractories, at the  same time, high temperature performance major improvements, and extens the life of refractory products.

Microsilica fume widely used in the refractory industry following.

Replace aluminum oxide mud for refractories.

As additives production unshaped and amorphous refractory products,its strength,high temperature performance greatly improved.

Shing drums for the overall combination of procoagulant casting agent

Other refractory products cohesion agent, binder, procoagulant agent, additives.


 Application area:                         


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

• Greatly improve its density, strength and high temperature performance.

3) Cementitous Repair Products (Mortars & Grouts)

• Low permeability, increase resistance from chlorides, acids, nitrates and sulfate etc

4) Oil Well Grouting

• Increase durability and compressive strength, decrease permeability, better control of gas leakage

5) Concrete Tile, roofing & wallboard,panels

• Lightweight and improve the strength

6) Polymers & rubber product

7) other application, such as waterglass industry, thermal insulation material etc.
