Refractory Micro silica/Silica fume Another Feature : Refractory

RefractoryMicro silica/Silica fume is a very fine pozzolanic material, composed of amorphous silica produced by electric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon alloys. Micro silica/Silica fume is also called as silica fume, fumed silica, silica dust, which is widely used in concretes field and refractorys field. The Micro silica/Silica fume used in refractory has a minimum of 94% content of silica.And this densified Micro silica/Silica fume reaches national first grade standard,80% of granularity is less than 0.1 um with a maximum of 0.3 um.

Application of RefractoryMicro silica/Silica fumein Refractory

Refractory Micro silica/Silica fume in refractory is a highly effective pozzolanic material. The functions of adding Micro silica/Silica fume are as follows:

Enhancing the fluid of pouring refractory

Reducing the volume of used water

Easy to shape

Raising the production efficiency

Microstructure for gap filling

Rising the compact and intensity of refractory

Enhancing elevated temperature strength and thermal shock of refractory.

Minimizes rebound loss
