description of microsilica products

microsilica (or silica fume) is amorphous, powdered sio2 collected by specially designed dust collector after the oxidization of silicon steam emitted by flue during the smelting of ferro-silicon alloy or industrial silicon. with an average particle size of 0.15~0.20 crystalline m and a specific surface area of 15,000 ~20000m 2 /kg, the silicon powder has a strong surface activity.

the main component of micro microsilica is amorphous silica, and the rising furnace gas also contains impurities, such as free c, fe2o3, cao, k2o, na2o and so on. the color of silica powder changes from white, grey to grey and deep grey as c and fe2o3 content increases.

the microsilica  directly after dust collection is called raw ash, whose bulk density is 150~300kg/m3. for the convenience of transportation and engineering application, the original ash can also be encrypted.

application of silicon powder

the properties of microsilica are mainly shown in two aspects: volcanic ash activity and microparticle property. therefore, microsilica is mostly used as filler and modified additive.

used for high performance concrete, improve concrete strength, performance and extend concrete life

used for refractories, enhance fluidity, reduce water consumption, improve product strength and durability

used for dry powder mortar, grouting material, improve early strength

used for wear-resistant floor, increase fluidity and improve abrasion resistance

used for paint, paint, resin, rubber and other polymer material filler
