Microsilica (Silica Fume) is a mineral composed of ultrafine amorphous spheres of silicon dioxide (SiO2), produced during the manufacture of silicon or ferrosilicon. The average particle is 0.15-0.20 micron in diameter. Specific Surface Area is ranging from 15, 000 to 20, 000 m2/kg, has dynamic surface activity.
The main ingredient of silica fume is amorphous silicon dioxide, as the rising of furnace gas, there are some impurities, such as floating C, Fe2O3 CaO K2O Na2O and so on. The colors of silica fume range from white, hoary, grey to dark grey as the rise of C, Fe2O3 content.
At present the classification standards of silica fume industry is based on the activated SiO2 content, Silica fume can be divided into 900D,900U,920D,920U,940D,940U,960U,970U. D means Densified, U means half-desified or undesified. According to the different application fields, our product is divided into engineering level, refractories level, flooring level, mix level,.We can provide the most applicable grades silica fume according to different customers¡¯ need, and ensure the product quality stability. |
