Refractory Micro silica/Silica fume Another Feature : Refractory Refractory Micro 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 Refractory Micro silica/Silica fume in RefractoryRefractory 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 refractoryReducing the volume of used waterEasy to shapeRaising the production efficiencyMicrostructure for gap fillingRising the compact and intensity of refractoryEnhancing elevated temperature strength and thermal shock of refractory.Minimizes rebound lossSpecification of Refractory Micro silica/Silica fume in RefractoryAnalysisResultResultResultSF95SF96SF97SiO2(%)95.5096.5097.30H2O(%)1.40.80.6Loss on Ignition2.01.00.8Cl(%)0.090.090.07Bulk Density (kg/m3)300-400300-400300-400Used Field of Refractory Micro silica/Silica fume in Refractory High performance refractory castable pre-formed shape Large scale iron runner, steel ladel and air brick Gravity refractory castable drying wet jet material Oxide combined Silica Carbide product High temperature calcium silicate light heat-insulating material High temperature and abrasion-proof material or products Corundum and ceramic products Sialon combined products
