sillica powder price, SiO2 micronized silica amorphous silicon powder for matting
The main ingredient of silica fume is amorphous Amorphous Silicon Powder, 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 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, our product can be divided into 900D,900U,920D,920U,940D,940U, " D"means Densified," U " means half-desified or undesified.
